· Also, cyanide leaching is used to process gold in the Aghdareh mine . The main problem in extraction is achieving an acceptable separation of Au from its ore. Thus, the effects of the main controllable parameters affecting gold recovery are evaluated, discussed and optimized. In this study, an experimental design technique, the response surface method (RSM) using central composite design .

SXEW technology involves leaching (the process of dissolving useful ingredients with a solution) in atmospheric conditions of copper ore heaps by means of diluted sulphuric acid. Folowing leaching, the pregnant leaching solution is transported via a drainage system to the next stage. In an SXEW reactor, the first process to take place is solvent extraction, which involves

Leaching. 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 SXEW (solvent extraction/electrowinning). Advantages of these processes are: Much ...

· Nitrate leaching in soils is the process of it gradually being moved down into the soil via soil moisture. It is determined by soil characteristics and water concentrations. Movement rates out of the root zones will vary. The rapidity of movement is considerably higher in sandy soils compared to clay soils. Knowing your soil types and zones within your fields are essential to managing leaching ...
