copper sulphide ore. In the absence of an economic technology to process this material it was mined as waste. Since the mid 1990s, Escondida and, in particular, BHP Billiton has been developing technology to process low-grade sulphide ores through bacterially assisted leaching to produce copper cathode. The development of this technology

A two-dimensional (2-D) model for a heap or dump bioleaching of a copper ore containing mainly chalcocite and pyrite has been developed. The rate of

The changes in copper content in the ore with the time of exploitation at the RTB mines [9] Oxide copper ore, mixed oxide-sulphide ores and low-grade copper sulphide ore, which, for economic reasons, cannot be enriched by flotation, may be processed by leaching methods. Agents for leaching copper

Disclosed is a method of efficiently leaching copper not only from a readily-soluble copper ore but also a poorly-soluble copper sulfide ore partially containing or consisting of chalcopyrite and/or covellite by means of ore heap leaching under versatile conditions for actual operation. Also disclosed is a method of leaching copper from a copper sulfide ore, including leaching

mainly for recovery of gold, copper, and uranium, from low-grade ores, mining and processing waste [2–6,16–19]. The twenty percent of the world’s copper production is accomplished by heap leaching of ores from mines and processing plants as well as waste ores from dumps and further processing by solvent extraction and electrowinning (SX,

silver and copper from these ores. The processes include heap leaching, agitation leaching and flotation. Geometallurgy is used to classify the various types of ore found in this complex ore body and to determine the optimum processing route for each ore type. Examples of the ore classification system are given.

ⓘ Dump leaching. Dump leaching is an industrial process to extract precious metals and copper from ores. Dump leaching is similar to heap leaching, however in the case of dump leaching ore is taken directly from the mine and stacked on the leach pad without crushing where, in the case of gold and silver, the dump is irrigated with a dilute cyanide solution that

A two-dimensional (2-D) model for a heap or dump bioleaching of a copper ore containing mainly chalcocite and pyrite has been developed. The rate of the mineral sulfide dissolution was related to,

Disclosed is a method of efficiently leaching copper not only from a readily-soluble copper ore but also a poorly-soluble copper sulfide ore partially containing or consisting of chalcopyrite and/or covellite by means of ore heap leaching under versatile conditions for actual operation. Also disclosed is a method of leaching copper from a copper sulfide ore, including leaching

The possibility of copper ore leaching of the Udokanskoe deposit using sulfuric acid with pH 0.4 at negative values of temperature and applying acidophilic chemolithotrophic microorganisms at positive values of temperature and low pH values was shown.

The leaching of sulfide minerals distinguishes bioleaching from conventional acid leaching. Bioleaching involves the use of microorganisms to catalyze the oxidation of iron sulfides to create ferric sulfate and sulfuric acid. Bioleaching is used today in commercial operations to process ores of copper, nickel, cobalt, zinc and uranium.

02-01-2019· Ruan et al. discussed the use of bioheap leaching–SX–EW technique used at Zijinshan copper plant in China to treat secondary copper sulfide ores. Megaw et al. [ 79 ] presented an alternate process for copper sulfate production that includes crushing and screening of the ores, heap-bioleaching, SX, and copper sulfate EW at remote location for

The sulfide ores are beneficiated in flotation cells, while the oxide ores are generally leached. First the copper ore from a open pit mine is blasted, loaded and transported to the primary crushers. Then the ore is crushed and screened, with the fine sulfide ore (~-0.5 mm) going to froth flotation cells for recovery of copper. The coarser ore,

Sulfide ores. Secondary sulfides – those formed by supergene secondary enrichment – are resistant to sulfuric leaching.These ores are a mixture of copper carbonate, sulfate, phosphate, and oxide minerals and secondary sulfide minerals, dominantly chalcocite but other minerals such as digenite can be important in some deposits.. Supergene ores rich in sulfides may be

Dump leaching has mostly been applied to gold, silver, and copper ores, whereas heap leaching has been applied to many different minerals including copper, gold, silver, ura-nium, vanadium, zinc, nickel, and cobalt. However, as the principal applications are copper and precious metals, most of the following discussion will refer to these metals.
