Using Little Red Riding Hood as an analogy in his opening remarks to the IMARC conference, Matt Canavan, minister for Resources and Northern Australia, explained that those in the green activist movement so often present themselves as the Big Bad Wolf. “They make threats, they inflate their support base and they build themselves up to be scary to all,” Engineering & Mining Journal, Volume 220, Issue 11, (ISSN 0095-8948) is Canavan said. “However, when it comes to actually blowing something over, they published monthly by Mining Media International, Inc., 11655 Central Parkway, are so often shown to be more huff than puff.

The future in scaffolding construction is digital – and it’s called SIM

SIM (Scaffolding Information Modelling) is an intelligent 3D model-based process that gives contractors, EPCs and plant owners the insight and tools to more efficiently plan, design, construct, and manage scaffoldings and other temporary works structures – it also ensures simple access to BIM. With the integrated LayPLAN Suite, Layher is providing its customers with an effective tool for SIM.

LayPLAN CLASSIC enables automated planning of predefined scaffolding applications – if required even with temporary roof structures. For complex scaffolding structures as part of large-scale engineering scaffolding, there is also LayPLAN CAD. Dependable 3D planning of scaffolding structures without collisions is just one of many benefits. Added to that are realistic visualisation of scaffolding, to allow work to be coordinated with other trades or for construction sequence simulation, transfer of the scaffolding planning to structural analysis programs, and output of material lists and assembly plans. Transparency at every work step results in a reduction in costs and an increase in safety and profitability.

When mining clients time and money.” TruScan is used in pulps, comparison between TruScan and any lab analysis is within the range of error seen when comparing one lab to another. When averaging the continuous scan data from rock core or chip scanning, TruScan has been proven to reveal a very strong correlation with lab assay along the same scanning interval. “TruScan also reveals the enormous heterogeneity in elemen- tal concentrations along the same interval. This accuracy, paired with detailed data density, can be very useful for geological in- terpretation and conceptual models,” said Mike Ravella, vice president of geological data services at Boart Longyear. TruScan is specifically calibrated to all elemental concentra- tions observed for each specific rock type. The process requires first sending samples to a lab for analysis to allow for calibration of the TruScan scanning tools. This typically occurs before the TruScan unit arrives at the mine site to maximize the efficiency of the technology. Ravella said, “It is well worth the effort in the beginning, Boart Longyear says its TruScan core-sample analysis service can detect a variety of and extremely cost effective for the long term, to complete a minerals beyond the range of traditional XRF technology.

TOMRA Updates COM Ore Sorter TOMRA Sorting Solutions, a Norwegian company, announced a major upgrade of its COM Series sensor-based sorting system in October 2018. The new COM XRT 2.0 sorters, according to TOMRA, feature higher belt speed and throughput, along with increased wear resistance and longer component lifetime, with a design that provides easier access to replaceable components. Ines Hartwig, product manager at TOMRA Sorting-Mining, said valuable experience gained over the past 15 years through monitoring and maintaining TOMRA COM XRT units operating in the field was incorporated into the design of the COM XRT 2.0. “Our sorters have been operating under harsh conditions in both hot and cold climates, sorting wet and dry feed across a wide range of commodities,” said Hartwig.

Since 2000, global steelmaking ca- pacity has increased by 1.178 billion mt. Meanwhile, steel production over the same period, 2000-2018, rose from 848 million mt to 1,808 million mt. Hence, overcapac- ity has increased from 208 million mt in 2000 to 426 million mt in 2018. How- ever, expressed as a utilization ratio, this is an improvement from 80% in 2000 to the previously discussed 81% in 2018. It is, however, only recently that the capaci- ty utilization ratio has increased. In 2015, the utilization ratio was at its lowest during recent years and fell to 70%. It is also the year with the highest recorded capacity of 2.334 billion mt. Since then, more steel capacity has been shut down than what has been installed while at the same time, Production capacity at Vale’s S11D project in Carajas, Brazil, has increased in both 2017 and 2018.

In 2018, 51% of total world crude steel was produced in China, a slight increase from the year before. According to the OECD, global steel- making capacity remained nearly un- changed in 2018, after declines in capacity for both 2016 and 2017.

That would generate an additional demand of roughly 61 million mt of iron ore globally. Global iron ore production in 2018 increased by 23 million mt, less than demand. The iron ore market was thus fairly balanced during 2018 with stable prices. But with the January Bru- madinho dam disaster, the iron ore mar- ket came into a clear deficit and iron ore prices have been high so far during 2019. For the first nine months of 2019, six major companies reported quarterly figures produced 774 million mt. This represents a decline of 6.3% compared to the same period last year. Vale shows the largest decline, down 21%, but it is inter- esting to note that all Big 3 shows reduced production. Further, Brazilian exports for the period January-September 2019 de- creased with 14% compared to the same period in 2018. Chinese imports during the period January-August declined by 3.3% compared to the same period in 2018. Chinese imports thus totaled 686 million mt for the first 8 months, or 1,029 million mt on an annualized rate. The spot price for 62% Fe fines deliv- ered in China will probably remain rela- tively high for the rest of 2019, with the caveat that iron ore demand from China may drop during the winter months caus- ing a restocking at Chinese ports. How- ever, looking at 2020 growth in steel, as discussed earlier, is forecast to be lower than 2019. Further, as pointed out, scrap may take a larger share of the burden than previously. This, in combination with the completion of Vale’s S11D and the gradual increase of production and export from Vale as well as the other big Aus- tralian producers producing at capacity peak, Rio Tinto estimates an increase in production by roughly 12% for fiscal year 2020 and BHP forecasts an increase of around 2% for 2019, the iron ore market is set for a readjustment. Iron ore production capacity will prob- ably increase faster than iron ore demand, which should put the spot iron ore 62% Fe

So, how can engineers determine the safe depth limit for an open pit and whether to continue mining from the sur- face or head underground?

Our EV drive integrates long cycle life, data-rich lithium batteries and high efficiency, high-torque electric motors, along with onboard chargers so that our entire fleet of BEV units is able to charge during a shift from mines’ existing electrical grids. “Plus, when we sell a BEV, we also have the field service expertise, and operator and maintenance training to support it.” As far as jurisdictions go, Ontario is currently at the forefront of the BEV rev- olution.

One of the largest safety concerns is the use of jackleg drills for roof bolting. Operators are exposed to hazards such as rock falling from the roof, rib, and face; tripping hazards; bending, twisting, and lifting hazards, high noise levels and ex- haust fumes. The continual operation of handheld equipment can also adversely affect the long-term health of operators and result in higher personnel turnover rates for mining companies.

sets and even cable bolts. They are rated to hold up to 30 metric tons (mt), and around 30 to 45 bolt installations can be performed per hour. Thanks to the reduction in cycle times, Barminco was able to increase develop- ment rates at Dugald River by more than 50%. Sandvik said that since implement- ing the MD bolt, Barminco has developed up to 950 m in a month using two Sandvik jumbos and consistently achieves 800 m. Barminco and Sandvik have also collaborated to develop a new meshing clamp solution that the mining services provider expects will improve ground sup- port cycle times even further. One-step Bolting Minova has also been working on a one- step bolting technology to make rock bolt- ing safer, faster and more efficient. The company has combined the ad- vantages of its self-drilling anchor (SDA) bolts and injectable, two component bulk resin grouts to create what it calls “a unique offering for the hard-rock mining environment.” This technology reduces manual mate- rial handling and improves overall instal- lation efficiency. The immediate bonding of the resin makes it possible to load the bolts without leaving the borehole and, after several years of development, the system was successfully trialed at LKAB’s Malmberget mine in Sweden as part of the Sustainable Intelligent Mining Sys- tems (SIMS) project. SIMS is part of Horizon 2020, the Eu- ropean Union’s most extensive research and innovation program. The WP7 work package, which includes cooperation from Minova, Epiroc and other mem- bers, aims to demonstrate state-of-the-art ground support methodology, ground con- trol techniques and monitoring technolo- Operator loading the carousel with rock bolts on a Boltec E rig.

www.e-mj.com NOVEMBER 2019 • E&MJ 59 RUSSIAN GOLD Climbing to New Heights Political uncertainty could make Russia the world’s biggest gold producer By Vladislav Vorotnikov

Everyone believes that Russia’s heavy gold buying, which has hit a six-year high of 145 mt in the first half of 2019, is a political move inspired by the grow- ing risk of sanctions. Over the past few years, Russian officials have repeatedly said that gold stockpiling is an attempt to reduce the Central Bank’s U.S. Trea- sury holdings, as a means to “de-dollar- ize” the national economy. Attracting Foreign Investment To accelerate growth in the industry and get more gold, the Russian government is now considering inviting foreign compa- nies to develop a large number of small deposits located across the country. In early 2019, the Russian Nature Ministry proposed to introduce a simpler procedure for permitting deposits with gold reserves below 200 mt for non-Russian companies. “For a non-Russian company to get Russia may nearly double gold production in the coming decade thanks to a weak ruble.

Many (93%) of the gold mining companies said they see Russian gold production growing as new deposits are developed. The demand for gold in Russia is set to grow even further, as Russian Presi- dent Vladimir Putin has recently signed a bill cancelling a 20% VAT on gold in- vestments.

The mixedROW footprint, and higher profits, according to the company, which describes the system as the first-of-its-kind because it concur- rently exploits the characteristics of two separate technologies. When nextSTEP machines are placed at the beginning of a row, they can recover coarse material us- ing the least amount of energy possible, said FLS, and this positioning enables mixedROW machines to lower energy con- sumption by between 15%-40% while in- creasing recovery by up to 5%. In the mixedROW system, WEM- CO machines are placed at the end of a row, which increases both coarse and fine particle recovery as they are capable of treating a wide range of particle siz- es, said FLS. The elevated rotor position within the machine also reduces energy consumption because the froth only has a short distance to travel. The company claims the mixedROW machines have the lowest head loss on the market, using an engineered system of dart valves that al- low efficient transfer of slurry from one tank to another without significant losses. Pointing out that flotation losses now commonly reach 50% and sometimes go as high as 90% for coarse particles, FLS said it also has worked to develop a prod- uct that allows customers to have more control over the froth recovery process. The resultant Froth Recovery Upgrade package offers a range of equipment engineered to improve the productivity of froth recovery, while minimizing the losses of valuable particles, according to the company, which claims the package finds solutions to flaws found in original froth-recovery technology. Major features of the package include: • Actuators that control the position of the improved dart valves inside the flo- tation cells. • Level sensors with no moving parts, that can accurately measure slurry levels. Among the features included in FLSmidth’s Froth Recovery Upgrade package are radial froth crowders designed for • Radial froth crowders designed for greater flexibility and control. According to the company, they reduce top-of-froth surface area and increase froth greater flexibility and control.

The result of these improvements, said FLS, is quicker reactions to flow and slurry density changes, thus boosting flo- tation machine performance. According to the company, the Froth Recovery Up- grade package will deliver better recovery at the same grade or increased grade at the same recovery.

Newly released 2019 global exploration budget data from S&P’s Corporate Explo- ration Strategies reveals that the industry recovery, which began in late 2016, fal- tered this year. The global nonferrous ex- ploration budget is down by 3% year over year to $9.8 billion in 2019 from $10.1 billion in 2018. “Difficult market conditions and high-profile mergers and acquisitions (M&A) activity have unsurprisingly im- pacted budgets the most, as the amount of money being raised by companies dropped sharply from November 2018 through February of this year,” said Mark Ferguson, associate director of metals and mining research at S&P Global Market In- telligence. “We are encouraged, however, are the most notable, as the post-merg- er commodities have decreased slightly, by some positive signs, such as the rising er Newmont Goldcorp and Barrick Gold with the exception of diamonds, which number of active companies, and copper have allocated about $48 million and has posted its first increase in six years. recording a year-over-year increase.” $54 million less, respectively, than the Comparing budgets by the regions host- “As the market remains volatile, we totals budgeted by the pairs of separate ing targeted projects, Australia’s nonfer- anticipate exploration budgets remain- companies in 2018. rous allocations have increased the most, ing relatively flat in 2020, as any increase Gold explorers have lowered their bud- by $199 million to $1.53 billion, surpass- to gold budgets will likely be offset by get by $559 million to $4.29 billion in ing Canada for the first time since 2001. lower allocations to other commodities,” 2019, the largest decrease for any com- Canada has slid by $134 million to fourth Ferguson added. modity, while allocations for base metals place with $1.31 billion.
