Heap Leaching with Solvent Extraction – Electrowinning (SX-EW) Heap leaching has also gained increased attention as a result of its demonstrated success in being combined with the SX-EW process, most notably in the copper industry.
New techniques for tailings treatment and sulfide ore recovery will see low-cost environmentally friendly heap leaching take another giant leap forward.
SX-EW, or the Solvent Extraction – Electrowinning approach to lateritic ore beneficiation, is a hydrometallurgical method that relies on leaching, extractants, and electrowinning to produce nickel from ore.
Copper extraction refers to the methods used to obtaining copper from its ores. The conversion of copper consists of a series of chemical, physical, and electrochemical processes. The conversion of copper consists of a series of chemical, physical, and electrochemical processes.
In what looks like a lucky coincidence, sulfuric acid is needed to treat oxide ores in processes called leaching and SX-EW (Solvent Extraction Electrowinning). Contact Us. Copper Mining and Processing: Processing of Copper Ores .
In what looks like a lucky coincidence, sulfuric acid is needed to treat oxide ores in processes called leaching and SX-EW (Solvent Extraction – Electrowinning). The acid would have to be made anyway as it would be environmentally unacceptable to release sulfur dioxide gas into the atmosphere.

The first step of the SX process is leaching the ore with a weak acid solution, which is generally sulfuric acid. From the leaching step, a pregnant leach solution is recovered and
2) Heap Leaching: Ore is crushed, agglomerated and charged to a heap, in a container lined with an impervious layer. Lixiviant is then irrigated on top of the heap, diffused through the heap, and is eventually collected and pumped out for further processing.

Copper Production Technology The last boomin technological innovation for the copper industry occurred in the first two dec-ades of this century, whenopen pit mining, flo- tation concentration,and the reverberatory smelter were adapted to porphyry copper ores. With the exception of leaching-solvent extrac-tion-electrowinning, the basic methods ...
SX-EW 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 situ leaching, ion exchange, solvent extraction, electrowinning, and precipitation. Crushing and grinding is the most energy intensive. The methods selected vary according to ore characteristics and economic factors.

Bacterial leaching, combined with SX/EW, offers a method of exploiting small ore bodies with a minimum of capital investment. Most commercial operations leaching copper from ore dumps are located in the Southern Hemisphere in Australia, Chile, Myanmar and Peru.
There are three fundamental steps to SX-EW: ore leaching, solvent extraction, and electrowinning. The first step consists of leaching the copper ore (which may be as prepared ore piles; pre-existing low grade, waste, or oxide dumps; or even in-situ material) with a …
Traditional methods viz – ore sieving, washing, etc. are obsolete and uneconomical. Pyro-metallurgy is highly costly and non-viable for low-grade ores. Leaching is the only process to extract metallic content from the low-grade ores.
