Copper extraction

Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors. As in all mining operations, the ore must usually be Get price

Copper processing

Extraction and refining The extraction of copper from ore is normally carried out in three major steps. The first step, mineral processing, is to liberate the copper minerals and remove waste constituents—such as alumina, limestone, pyrite, and silica—so that the copper minerals and other nonferrous minerals of value are concentrated into a product containing between 20 and 30 percent Get price

Iron Control in Zinc Pressure Leach Processes

The volume of the iron residue and its stability are factors that must be addressed in the disposal of tailings and long-term storage. Throughout the 1980s and the 1990s, the application of the Dynatec zinc pressure leach process to the treatment of a wide variety of zinc-bearing concentrates has been extensively studied. Get price

Extraction of Platinum Group Metals

2017/10/2About 80% of the worlds' reserves for platinum group metals (PGMs) are in South Africa's Bushveld Igneous Complex. Processing of PGM involves comminution, flotation, smelting, converting, base metals refinery and precious metals refinery. Due to increasing chrome content in the feed and the challenges associated with operating high chrome feed, alternative routes to smelting of PGM are Get price

Iron Production

Iron Production Last updated Save as PDF Page ID 649 Introduction Outside links References The production of iron from its ore involves an oxidation-reduction reaction carried out in a blast furnace. Iron ore is usually a mixture of iron and vast quantities of impurities Get price

Bayer process

Bauxite ore is a mixture of hydrated aluminium oxides and compounds of other elements such as iron. The aluminium compounds in the bauxite may be present as gibbsite 2(Al(OH) 3), bhmite (γ-AlO(OH)) or diaspore (α-AlO(OH)); the different forms of the aluminium component and the impurities dictate the extraction conditions.

In Place Mining

With declining ore grades and the need to mine deeper ore bodies, we need to utilise new methods that reduce rock movement, mine more selectively, and emphasise quality over quantity. Mining3 is leading a transformational initiative called In Place mining, which is motivated by the concept of minimal rock movement and processing "In Place". Get price
