Copper Mining and Processing: Processing Copper Ores

A. Processing of Oxide OreB. Processing of Sulfide OreC. Recycling Copper

Oxide ores are generally processed using hydrometallurgy. This process uses aqueous (water-based) solutions to extract and purify copper from copper oxide ores at ordinary temperatures, usually in three steps: heap leaching, solvent extraction, and electrowinning. Heap Leachingis the process of using percolating chemical solutions to leach out meta...

Agglomeration and leaching behaviors of copper oxides

2021年7月18日  The chemical binder is one of the critical factors affecting ore agglomeration behavior and leaching efficiency. In this study, we investigated the effect of the type of binder and mass fraction of the H2SO4 solution used on the curing, soaking, and leaching behavior of agglomerations. The results revealed that Portland cement

Copper Ore an overview ScienceDirect Topics

In most cases, the thin-layer process was used where crushed ores (80% −0.5 in) were stacked in heaps of 3–8 m height after agglomeration and sprayed at flow rates of 6–40 Lhour −1 m −2 with 15–90 days duration for copper oxides and 10–18 months for sulfides. Of note, 80%–85% copper extraction was commonly achieved.

Heap Leaching Oxide and Sulfide Copper Ores

2019年6月22日  Heap leaching is a simple means of recovering copper from oxide and oxide-sulfide ores. Although this method requires relatively low capital investment, it suffers from low copper recoveries and relatively high acid consumption. The objectives of this study were (1) to determine what factors influence these shortcomings, and (2) to establish a

Geometallurgy of cobalt ores: A review ScienceDirect

2021年1月1日  Due to its low concentration in ores, cobalt is usually considered to be a companion metal which is of limited economic interest. The bulk of global cobalt production emanates as a by-product of extraction of commodities such as copper (~55%), nickel (~35%), and arsenic (Azevedo et al., 2018, Smith, 2001).The only exceptions, which

[PDF] NICKEL SULFIDE VERSUS LATERITE Semantic Scholar

There are widespread nickel resources around the world, but divided principally between nickel sulfide or laterite (oxide) resources. Historically production has been dominated by sulfide ores but future production is increasing shifting to laterite ores. The principal reason for this historically is that sulfide ores are easier to process, through conventional mining,

Some sulfides are mined as sources of such metals as zinc, lead, copper, and tin. Carbonates. These are based on the carbonate ion, (CO 3) 2–. Calcite, CaCO 3, and dolomite, CaMg(CO 3)2, are carbonate minerals. Carbonate minerals tend to dissolve relatively easily in water, especially acid water, and natural rain water is slightly acid.
