  • Understanding Fluid–Rock Interactions and Lixiviant/Oxidant Behaviour for the In-Situ Recovery of Metals from Deep Ore Bodies
    School of Earth and Planetary Science Department of Applied Geology Understanding Fluid–Rock Interactions and Lixiviant/Oxidant Behaviour for the In-situ Recovery of Metals from Deep Ore Bodies Tania Marcela Hidalgo Rosero This thesis is presented for the degree of Doctor of Philosophy of Curtin University February 2020 1 Declaration __________________________________________________________________________ Declaration To the best of my knowledge and belief, I declare that this work of thesis contains no material published by any other person, except where due acknowledgements have been made. This thesis contains no material which has been accepted for the award of any other degree or diploma in any university. Tania Marcela Hidalgo Rosero Date: 28/01/2020 2 Abstract __________________________________________________________________________ Abstract In-situ recovery (ISR) processing has been recognised as a possible alternative to open- pit mining, especially for low-grade resources. In ISR, the fluid–rock interaction between the target ore and the lixiviant results in valuable- (and gangue-) metal dissolution. This interaction is achieved by the injection and recovery of fluid by means of strategically positioned wells. Although the application of ISR has become more common (ISR remains the preferential processing technique for uranium and has been applied in pilot programs for treating oxide zones in copper deposits), its application to hard-rock refractory and low-grade copper-sulfide deposits is still under development. This research is focused on the possible application of ISR to primary copper sulfides usually found as deep ores. Lixiviant/oxidant selection is an important aspect to consider during planning and operation in the ISR of copper-sulfide ores.

  • A History of Tailings1
    A HISTORY OF MINERAL CONCENTRATION: A HISTORY OF TAILINGS1 by Timothy c. Richmond2 Abstract: The extraction of mineral values from the earth for beneficial use has been a human activity- since long before recorded history. Methodologies were little changed until the late 19th century. The nearly simultaneous developments of a method to produce steel of a uniform carbon content and the means to generate electrical power gave man the ability to process huge volumes of ores of ever decreasing purity. The tailings or waste products of mineral processing were traditionally discharged into adjacent streams, lakes, the sea or in piles on dry land. Their confinement apparently began in the early 20th century as a means for possible future mineral recovery, for the recycling of water in arid regions and/or in response to growing concerns for water pollution control. Additional Key Words: Mineral Beneficiation " ... for since Nature usually creates metals in an impure state, mixed with earth, stones, and solidified juices, it is necessary to separate most of these impurities from the ores as far as can be, and therefore I will now describe the methods by which the ores are sorted, broken with hammers, burnt, crushed with stamps, ground into powder, sifted, washed ..•.

  • Identification and Description of Mineral Processing Sectors And
    V. SUMMARY OF FINDINGS As shown in Exhibit 5-1, EPA determined that 48 commodity sectors generated a total of 527 waste streams that could be classified as either extraction/beneficiation or mineral processing wastes. After careful review, EPA determined that 41 com modity sectors generated a total of 354 waste streams that could be designated as mineral processing wastes. Exhibit 5-2 presents the 354 mineral processing wastes by commodity sector. Of these 354 waste streams, EPA has sufficient information (based on either analytical test data or engineering judgment) to determine that 148 waste streams are potentially RCRA hazardous wastes because they may exhibit one or more of the RCRA hazardous characteristics: toxicity, ignitability, corro sivity, or reactivity. Exhibit 5-3 presents the 148 RCRA hazardous mineral processing wastes that will be subject to the Land Disposal Restrictions. Exhibit 5-4 identifies the mineral processing commodity sectors that generate RCRA hazardous mineral processing wastes that are likely to be subject to the Land D isposal Restrictions. Exhibit 5-4 also summarizes the total number of hazardous waste streams by sector and the estimated total volume of hazardous wastes generated annually. At this time, however, EPA has insufficient information to determine whether the following nine sectors also generate wastes that could be classified as mineral processing wastes: Bromine, Gemstones, Iodine, Lithium, Lithium Carbonate, Soda Ash, Sodium Sulfate, and Strontium.

  • MINING in BAKER COUNTY, 1861 to 1959* by Norman S
    Vol.21, No.3 THE ORE.- BIN 21 March 1959 Portland, Oregon STATE OF OREGON DEPARTMENT OF GEOLOGY AND MINERAL INDUSTRIES Head Office: 1069 State Office Bldg., Portland I, Oregon Telephone: CApitol 6-2161, Ext. 488 Field Offices 2033 First Street 239 S. E. "H"Street Baker Grants Pass *************************** MINING IN BAKER COUNTY, 1861 to 1959* By Norman S. Wagner** Introduction Baker County mining began with the discovery of gold in 'Griffin Gulch in 1861. This and the develop­ ment which followed at Auburn represent gold mining at its historic best. Since 1861, much water has flowed down the sluice boxes with respect to mineral resource development within the county. As a result, the dis­ covery story is left for historians to tell, and the following paragraphs are devoted to the high points of the many kinds of mining endeavors that occurred in Baker County between 1861 and 1959. Hydraulic and sluicing operations All of the earlier placer operations have one thing in common with Griffin Gulch and Auburn. This is that they were carried out by means of ground sluicing and hydraul icking, using generous amounts of hand labor. These means of handl ing placer ground continued in exclusive use throughout the first forty years of Baker County mining history. It wasn't until the present century that the more familiar bucket-line dredges and other kinds of mechanized digging and washing plants made their appearance. Even yet the old methods are still employed on a small scale in circumstances where ground conditions permit. The Rye Valley placers on Dixie Creek represent a notable example of an early discovery made shortly after 1862.

RESULTS AND DISCUSSION 3.1 Hazardousness Test. 3.2 Chemical and mineralogical characterization. 3.3 Leaching. 4. CONCLUSION. REFERENCES. 1. INTRODUCTION The generation of industrial solid waste constitutes an environmental problem that requires efforts for adequate disposal. Currently, in Brazil, solid waste management is standardized, with a classification determining the management according to its hazardous characteristics. ABNT NBR 10004 is a Brazilian Standard to solid waste and classifies its as: Class I (hazardous), Class II - A (non - hazardous and non - inert) and Class II - B (non - hazardous and inert) according to the concentration of elements that have potential risks to the environment and public health (ABNT NBR 10,004, 2004) A process with a large generation of wastes is the production of copper. Several studies in the last decades investigated routes to recovery copper and other metals of interest from the slag (solid waste from the foundry). In the case of primary production, the slag has copper contents between 0.5 and 2% and the volume generated is twice the refined metal (Schlesinger et al., 2011) In addition to primary copper production, there is a significant rate of the copper production from scrap/waste metal. Secondary copper production in Brazil in 2014 reached 23,600 tons, representing around 9% of domestic production.

  • Gold Extraction from Paleochannel Ores Using an Aerated Alkaline Glycine Lixiviant for Consideration in Heap and In-Situ Leaching Applications E.A
    Gold extraction from paleochannel ores using an aerated alkaline glycine lixiviant for consideration in heap and in-situ leaching applications E.A. Orabya,c, J.J. Eksteena*, A. Karrechb, M. Attarb aFaculty of Science and Engineering, Western Australian School of Mines: Minerals, Energy and Chemical Engineering, Curtin University, GPO Box U1987, Perth, WA 6845, Australia bDepartment of Civil, Environmental and Mining Engineering, The University of Western Australia, Australia c Mining and Metallurgical Engineering, Faculty of Engineering, Assiut University, Egypt *Corresponding Author: [email protected] ABSTRACT The decreasing grades of some gold deposits combined with the increasing depths, difficult surface topography, socioeconomic and geopolitical pressures often make the processing of such deposits infeasible by conventional mining, comminution and leaching technologies. To overcome these problems, the application of in-place, in-situ, and heap leaching often represent an optimal solution that minimises the capital and operating costs associated with mining and processing operations. Non- toxic, low cost lixiviants that are stable over an extended range of pH and Eh are required to provide any practical solution to ISL. Since ISL has the inherent benefit of increased natural rock temperature and pressure, glycine-based systems can be considered to extract valuable metals. Based on earlier studies on glycine leaching of pure gold foil, this research shows that Western Australian paleochannel ores are amenable to glycine-based ISL, at elevated alkalinity. The effects of pH, temperature, free glycine, ferric ions, sodium chloride and solids percentages on the kinetics of gold extraction were assessed. More than 85% of the gold can be extracted from ore with solutions containing 15 g/L glycine at pH 12.5 in 336 hours.

  • Extraction of Copper at Elevated Feed Concentrations R.E
    SGS MINERALS SERVICES TECHNICAL PAPER 2003-07 2003 EXTRACTION OF COPPER AT ELEVATED FEED CONCENTRATIONS R.E. MOLNAR, N. VERBAAN –– SGS ABSTRACT A number of flowsheets have been designed and operated, or are currently being considered, to extract copper from leach solutions having much more copper than the 4 g/L levels typically found in heap leach liquors. Dealing with these solutions has required that the envelope for “normal” copper solvent extraction be pushed beyond the usually considered limits. Others have published information on flowsheets to recover copper from leach liquors containing over 25 g/L copper. Secondary solvent extraction circuits are often required to attain satisfactory overall recoveries. This paper reviews some of the issues faced in three pilot plant circuits that were operated by SGS Lakefield Research to produce cathode copper from solutions containing 8 to 20 g/L Cu. The primary objective was to maximize copper extraction using one solvent extraction circuit. The role of feed acidity and the disposition of impurities such as iron and chloride are considered. The challenges of running short SX piloting campaigns are discussed. INTRODUCTION In more recent years hydrometallurgy is finding wider application in the treatment of complex ores that contain copper. Very often, the plant will need to process a Copper solvent extraction was originally sulphide concentrate rather than an oxidised copper ore that is readily leached at developed in the 1960’s to recover ambient conditions. It is probably going to be using more aggressive oxidative leaching copper from relatively dilute leach methods, for example, oxygen pressure leaching. Higher percent solids are employed solutions, typically heap leach liquors in the leaching stages both to keep plant sizes as small as practically possible, and to with copper tenors in the 1 to 4 g/L ensure that the heating requirements of the process are being fully met by oxidising range.

  • Copper Hydrometallurgy and Extraction from Chloride Media
    COPPER HYDROMETALLURGY AND EXTRACTION FROM CHLORIDE MEDIA JAN SZYMANOWSKI SK96K0015 Institute of Chemical Technology and Engineering, Poznan University of Technology, PI. Sktodowskiej-Curie 2, 60-965 Poznan, Poland The development of copper hydrometallurgy is presented and various processes proposed for copper recovery from sulphide concentrates are discussed. Leaching, extraction and stripping are considered, including reagents and processes. The extraction of copper from chloride solutions is discussed. Various extractants are presented and their use for copper transfer from chloride solutions to the organic phase and back to chloride and to sulphate solutions is discussed. Hydrometallurgy is used for copper recovery for more than 300 years. Already in 1670 the mine waters were treated with iron to precipitate copper. However, two hundred years were needed to process oxide ores by vat leaching and copper cementation with iron. The development most important to copper hydrometallurgy, both with respect to the growing number of its applications and for its future potential, has been solvent extraction (SX). 1 It started in 1968 in a small scale and in about 1974 in a large scale of about 100 000 tones/year copper. These operations have served as a stimulus for at least of 30 copper plants, recovering nearly 800 000 tonnes/year of copper with the application continuing to increase. New processes are now developed to recover copper from sulphide ores and concentrates, including CLEAR Process and CUPREX Process. Chloride-based processes play a key role in the metallurgical and chemical industries. 2 One of the most important factors responsible for the significant role of chloro-based processes is the ease of chlorine recycling.
