Sulfuric acid heap leaching of nickel. The technique is an acid heap leaching process like that of the copper method in that it uses sulfuric acid instead of cyanide solution to liquefy the target minerals from crushed ore. The process has been urbanized by European Nickel PLC for the rock laterite deposits of Turkey and the Balkans.
This method is an acid heap leaching method like that of the copper method in that it utilises sulfuric acid instead of cyanide solution to dissolve the target minerals from crushed ore. The amount of sulfuric acid required is much higher than for copper ores, as high as 1,000 kg of acid per tonne of ore, but 500 kg is more common.

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of % pure copper called cathodes, which will ultimately be made into products for everyday most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...
Copper extraction Wikipedia. Such oxide ores are usually leached by sulfuric acid, usually in a heap leaching or dump leaching process to liberate the copper minerals into a solution of sulfuric acid laden with copper sulfate in solution.
It forms as sulfuric acid percolates through the ore pile while the copper content of the ore is introduced in the aqueous solution. At some sites, drainage systems move the solution to the next processing stage using gravity; other sites use pumps. Butterfly and ball valves are good choices for PLS flow control.
The flowchart above shows how the smelting process of sulfide ores produces sulphur dioxide, which is converted to sulfuric acid. The chart below shows how acid is used to leach out copper ions creating lakes of blue copper sulfate solution from which copper is recovered in a solvent and then electrolytically refined in a process called solvent ...
Supergene sulfide ores rich in native copper minerals are refractory to treatment with sulfuric acid leaching on all practicable time scales, and the dense metal particles do not react with froth flotation media. Typically, if native copper is a minor part of a supergene profile it will not be recovered and will report to the tailings.
(L/SX/EW) process for copper recovery, considered by some to be one of the great advances in copper recovery technology of the past 100 years1, satisfies these criteria. Historical background When the sulphuric acid copper L/SX/EW flow sheet (Figure 1) was put forth by the Minerals Development Group of General Mills in 1960
This flowchart made of machinery icons explains or expresses in simple but clear terms the step of the Copper Mining and Copper Extraction Process. Starting from either openpit or underground mining and using a different relevant treatment method for oxide or sulphide copper mineral (ore). Having a quick look now at how porphyry ores are treated and the metals extracted.
Sulfuric acid – Manufacturing process of Sulfuric acid : Sulfuric acid is the largestvolume industrial chemical produced in the world (200 million tons per year). Concentrated sulfuric acid (9398 %) is used in the manufacture of fertilizers, explosives, dyes, and petroleum products.
The blister copper anodes are immersed in an electrolyte containing copper sulfate and sulfuric acid. Pure copper cathodes are arranged between the blister copper anodes and a current of over 200A passes through the solution. This is driven by a low voltage of about and so the process is safe. What happens in electrolysis?

Alena opens describing the heap leaching process for copper: Copper ore is excavated from the ground, crushed and then spread in uniform layers on a pad. A slow trickle of sulfuric acid is distributed over the pile, where it percolates to the bottom and a collection point.
A schematic diagram of the conventional process for the production of copper and the SX/EW process can be seen here. Conventional Copper Extraction . Conventionally, copper is recovered by a pyrometallurgical process known as smelting. In this process copper ore is mined, crushed, ground, concentrated, smelted and refined.
Sulfuric acid has many industrial purposes and is produced in greater quantities than any other chemical worldwide. In metal mining, sulfuric acid is used to leach copper oxide minerals. In one process, a solution of sulfuric acid laden with copper sulfate is stripped of copper via a solvent extraction and electro winning with the used sulfuric ...
