The pregnant liquors and wash waters obtained from the vat leaching operation are pumped to a precipitation plant where the copper is recovered by use of iron scrap. Inspiration Consolidated Copper Co. The ore treated in the vat leaching operation of the Inspiration Consolidated Copper Co. (fig. 22) is mixed oxide-sulfide ore.

The processing plant consisted of a smelter with reverberatory furnaces and torch furnaces, which were discontinuously active over the long time of its existence (Valenzuela, 1992). Besides the copper ore, pyrite was used as fuel and garnet skarn as well as carbonate rocks as flux.

Chuquicamata (Codelco)—1.6 mta. Codelco's Chuquicamata smelter is fed by the Chuquicamata (or Chuqui) copper mine, one of the world's largest open-pit copper mines in the world. Located in northern Chile, Chuqui's smelting facilities were initially installed in the early 1950s. 02. of 11.

The Basics of Copper Mining and Processing. Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. Using today's compact mining equipment, copper ore is extracted from the mine. After the ore is crushed, it's roasted, which helps to convert sulfides to oxides.

Concentrator Operations. The ores received into the plant, after conventional washing, crushing and grinding, are subjected to differential flotation for the recovery of sulphide copper mineral for smelting and oxide (or non-sulphide) copper minerals for leaching. Sources of feed materials to the concentrator are: (a) Nchanga West orebody.

3. Copper ore plant advantages. Dasen Mining has been specialized in copper flotation research for more than 20 years. Whether it is copper oxide or copper sulfide, our company's professional technical team will give the best beneficiation plan based on specific mineral indicators and experimental results.

4. Beneficiation of Copper Ore. The next step in processing is called beneficiation. This is the first step in concentrating the copper into a more useable form. 5. Smelting and Extraction. The next step in the process flow is smelting for sulfide ore concentrate and solvent extraction for oxide ore leach solution. 6.

The details of the copper-refining process depend on the type of minerals the copper is bound with. Copper ore that is rich in …

The bulk flotation and the sulfide flotation of copper from atmospheric leaching cake in the future copper ore processing plant at the Udokan deposit is planned to be carried out at pH 9.0–10.5 and 5–6, respectively. Lime milk will be used to form and maintain the pH medium. One problem in the flotation process is the presence of sludges.

Extraction of copper from suitable ore by leaching methods is generally assumed to cost less than the combined expense of concentration, smelting, and refining, and experimental data tend to confirm this opinion. At the Butte-Duluth plant, which is handling in excess of 100 tons of oxidized ore daily, the copper is said to cost $0.085 …

Ore processing flow: 1 Crushing: Use stone crushers to crush the copper ore to 0~5mm or 0~9mm. 2 Washing: Use a spiral classifier to wash away the clay and screen out copper ore with a qualified particle size. 3 Grinding: The electromagnetic feeder sends the copper ore with qualified particle size to the ball mill for grinding.

Typically, these operations treat over 50,000 t/d of ore with copper head grades below 1%, and sometimes as low as 0.3%. The economic viability of these mines depends on keeping operating costs per tonne of ore below the payable revenue per tonne. For these mines, energy is a significant fraction of operating cost and the main source of …

As a general approach in the simulation, the copper process and the HyS cycle plant were run simultaneously for each ore composition to solve (automatically) for the size of the HyS cycle (via using multiple Calculators and Design Spec units) by altering water input and circulating acid to meet the calculated demand from the copper plant. …

The ratio of overburden to ore is sometimes as high as 5 to 1. The ore itself averages less than 0.7% copper in US mines. Copper ore normally is crushed, ground, and concentrated, usually by flotation, to produce a beneficiated ore containing about 25% copper. The ore concentrates are reduced to the metallic state, most often by a ...
