Recovery of Copper by Solution Mining Methods

leaching of copper-bearing ores in the U.S The dissolved copper recovered by this operation was derived from the natural oxidation and leaching of sulfide mineralization in a major porphyry copper deposit located in the headwaters of Bingham Creek. This is the present site of the large-scale, open pit operation at Bingham Canyon, which

Acid Leaching - Copper Ore Treatment Method

May 23, 2017  PREPARATION OF THE COPPER ORE. This study is limited in general to percolation leaching as it is the most widely used method to give proper contact of solvent with the ore to effect extraction of the copper. One of the important factors in percolation leaching is the size reduction necessary for copper recovery within reasonable time limits.

Dissolution of copper and iron from malachite ore and ...

Mar 01, 2014  The present work describes an investigation of a chemical process for the recovery of copper and iron from malachite ore. For the dissolution of copper and iron, H 2 SO 4 was employed as well as H 2 O 2 as an oxidizing agent. The effects of reaction temperature and time, acid concentration, liquid-to-solid ratio and agitation rate on the copper and iron percentage were investigated.

Copper Recovery From Nitric Solution E-waste Recycling

Nov 26, 2017  Copper Recovery: We can use any piece of steel or iron For copper recovery from nitric solution. I used an iron pipe for copper recovery in the video. First, dip any piece of iron in nitric solution. If reaction starts immediately and you think that your metal is dissolving in solution then add water to the dilute nitric solution. I also added ...

Eliminating Copper from Gold Ore

Oct 11, 2015  The treated ore is then cyanided in the usual way and the gold recovered by electrolytic precipitation. Whether or not any precious metal was dissolved in the preliminary cyanide treatment was not stated. In another elimination method the copper mineral is dissolved out by means of ammonia after which the ore is cyanided as usual.

Copper mining. From ore to copper.

The ore is treated with dilute sulphuric acid. This trickles slowly through the ore dissolving copper to form copper sulphate. The copper is recovered by electrolytic refining. Advantages of this process are: much less energy is use than in traditional mining no waste gases are given off it can be used on ores with as little as 0.1% copper ...

LEACHING OF LOW-GRADE COPPER ORES: A CASE STUDY

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 can be acid, base, or salt solutions. Of all of these agents, sulphuric acid has been given the

Y. M. Zhao et al. 12 However, when 1% Na 2SO 3 was added, the copper extraction wasn’t down until 650 ˚C. This indicated that Na 2SO 3 can improve the degree of sulfating at high temperature. One possible reason is that the addition of Na 2SO 3 could prevent the decomposition of copper sulfate. Another possible reason is the exist of some com-

In general, the quality of precipitate in the cyanidation process will depend upon the nature of the ore being treated. The richer the pregnant solution is, the better the quality of the precipitate of gold and silver is, although this is modified by the presence of metals, such as copper, lead, zinc and iron. This behavior can be explained

Copper Mining and Production Processes Explained

Leaching offers an alternative to copper mining. First, the ore is treated with dilute sulphuric acid. This trickles slowly down through the ore, over a period of months, dissolving copper to form a weak solution of copper sulphate. The copper is then recovered by electrolysis. This process is known as SX-EW (solvent extraction/electrowinning).
