8 Grinding Media A key mining consumable

. Grinding media is used in the process of extracting minerals from ore, particularly in the fast growing copper and gold industries . Ore particles must be ground down to sufficiently small sizes so the contained metal species become ‘liberated’; i.e. free from gangue materials, prior to subsequent concentration processes . Grinding is carried out in large horizontal tumbling mills, partially filled with steel balls or rods (grinding media) . Mills require continuous refilling with new grinding media as they get consumed . Consumption of grinding media is related primarily to the volume of ore processed

Questions For personal use only use personal For

Appendix For personal use only use personal For Moly-Cop history

. In the 1930s, Armco’s Sheffield Steel of Kansas City produced the first heat-treated grinding ball alloyed with molybdenum and copper. The new ball significantly improved wear performance versus the quality levels of that time, and was patented and appropriately trademarked as Moly-Cop® . In 1961, Armco built its first grinding ball forging operation outside the USA - now known as Moly-Cop Chile. This began several decades of growth to build the international Moly-Cop business with grinding ball plants located strategically around the world to include Chile, Peru, Mexico, and Canada . In 2001, then owner GS Industries went into bankruptcy and sold the international Moly-Cop businesses to Anglo’s Scaw Metals in 2002. The original Kansas City ball plant restarted as an independent company in 2003 and became part of Arrium in 2007 . With Arrium’s acquisition of Moly-Cop, Kansas City has been reunited with the businesses it helped build, further enhancing

the strength and depth of the new Moly-Cop organisation For personal use only use personal For

52 CRUspi Longs index

. CRU is an independent, privately owned, business analysis and consultancy group focused on the mining, metals, power, cables, fertilizer and chemical sectors . Of particular interest to Moly-Cop’s business, CRU publishes a series of Steel Price Indices (CRUspi) intended to monitor the evolution of selected groups of steel product prices in various international markets . CRUspi Indices are constructed from actual information of numerous commercial transactions worldwide, following standardized surveying methodologies . CRUspi indices are published on a regular basis; the first Wednesday of every month . Since 2004, Moly-Cop has been using the CRUspi Longs Index as a reference for periodic price updating of both steel purchasing and grinding media sale contracts . The consistent application of the CRUspi Longs Index has allowed Moly-Cop to engage in long-term, variable pricing purchase/sale agreements . The CRUspi Longs Index will be representative for Moly-Cop as long as such reference is

accepted by its main bar suppliers. For personal use only use personal For
