Bioleaching involves the use of microorganisms to catalyze the oxidation of iron sulfides to create ferric sulfate and sulfuric acid. Ferric sulfate, which is a powerful oxidizing agent, then oxidizes the copper sulfide minerals and the copper contained is then leached by the sulfuric acid formed. In the case of uranium, the ferric sulfate.cobblestone jaw crusher feed sizeLearn More
Sep 26, 2019 · After crushing oxide-type copper ores, such as azurite (2CuCO 3 · Cu(OH)3), brochantite (CuSO 4), chrysocolla (CuSiO 3 · 2H 2 O) and cuprite (Cu2O), dilute sulfuric acid is applied to the surface of the material on leaching pads or in leaching tanks. As the acid trickles through the ore, it combines with the copper, producing a weak copperLearn More

For example, leaching copper ore containing malachite with dilute sulfuric acid changes the mineral composition, that is, malachite becomes a copper sulfate solution, and then replaces copper ions in the solution with iron filings to obtain metallic copperLearn More
Most copper leaching is done by piling broken ore ∼0.5% Cu into flat-surface 3–10m high 10 4 –10 5 m 2 heaps of ore and then sprinkling dilute sulfuric acid lixiviant on to the heap surface. The lixiviant trickles down through the heap and leaches copper from its minerals to produce a pregnant leach solution containing 1–5kg Cum −3Learn More

Feb 05, 2021 · Dilute sulfuric acid solutions containing from 30 to 35 grams per liter of acid are used to leach the ore. 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 scrapLearn More
The leaching of the "oxide" materials is relatively easy and relies on dump, vat and agitation leaching using dilute sulfuric acid solutions. Both the Asarco Ray Mine and the Silverbell Mine are leaching low-grade copper with weakly acidic solutionsLearn More
Dec 08, 2020 · Control of SO2 from smelters is commonly performed in a sulfuric acid plant. Use of a sulfuric acid plant to treat copper smelter effluent gas streams requires that particulate-free gas containing minimum SO2 concentrations, usually of at least 3 …Learn More
In 1968 there were only two widely practiced copper leaching processes using dilute sulphuric acid. The first process, vat leaching of high-grade copper oxide ore followed by EW of copper from the leach solution, produced low quality copper cathode at relatively high costLearn More
Sulfuric Acid metal mining, sulfuric acid is used to leach copper oxide minerals In one process, a solution of sulfuric acid laden , solution in mg, Q is the pump flow rate in liters per minute and T is the total time of sampling in minut Note thatLearn More

Sulfuric acid slag spiral classifier for gold spiral classifier is also called screw classifier the spiral classifier is widely used in the beneficiation plant to form a closed loop with the ball mill to split the ore or to classify the ore and fine mud grade the slurry during the spiral classifier mineral processing and dewater in washing operations sulfuric acidLearn More
Such aqueous acid leaching typically utilizes an aqueous solution of dilute sulfuric acid ("leachant"), which leaches, or dissolves, the copper from the ore. The aqueous acid leachant is typically sprayed on top of the heap or dump and allowed to percolate, or trickle, down by gravity between the ore piecesLearn More
