Technologies and Processes for Economical Recovery of Cu from Challenging Ores
摘要
Increasing demandDemand for copperCopper, along with decreasing availability of economic oxide and sulfideSulfide resources, is leading to alternative technologiesTechnology being investigated to recover this important metalMetal. Stockpiles of low-gradeGrade or refractoryRefractories ore are advantageous since miningMining costs are significantly decreased. However, many such ore bodies have challenges, including high gangue acid consumption or low acid-soluble copperCopper (ASCu). This paper explores various processingProcessing options available for such resources, highlighting the specific conditions under which they can be applied. Where technologiesTechnology have not been applied industrially yet, the problems that must be addressed are described.
