Crushing and Grinding You will note that the Oracle Ridge project has utilized a two-stage crushing circuit with a double acting jaw crusher and cone crusher. In order to utilize this system, the jaw crusher is oversized to produce all -5 material for the cone mill with a screen in closed circuit. Normally a three-stage crushing circuit would have been more conventional, but with

Technology improvements in copper mining operations have been the key factor for increasing productivity. Beyond dump leaching, the industry will increasingly use various heap leach techniques in SX-EW operations in the coming years in order to optimize recovery and maintain low production costs. They include: Finer comminution followed by agglomeration.

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source,
The Sepon Copper project is a patented copper leaching process comprised of crushing, acid grinding, acid flotation, pressure oxidation and a solvent extraction electro winning circuit designed to produce 60,000 t/y of cathode copper, which has subsequently been increased by Ausenco to 80,000 t/y.
The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in
improve the performance of the CIL (Carbon-in-Leach) circuit at copper-gold concentrators. Occlusion of gold by iron sulphide gangue minerals and the fine grain size of gold associated with them contribute to the low gold recovery in the CIL circuit. Fine grinding of the CIL feed increased gold recovery significantly from the leaching process

Abstract. High-pressure grinding rolls (HPGR) are an accepted, but continuously expanding, comminution technology. The copper industry has a growing need to process harder ores with progressively lower grades, more challenging metallurgy and increasing demand for efficient bacterial leaching applications.
The Outotec copper pressure leaching process combines our highly effective pressure oxidation and leaching technology with world-renowned VSF solvent extraction and electrowinning technology. The process also enables precious metals recovery from leaching residue with cyanide leaching technology. Recovers copper effectively from copper sulfides

atmospheric pressure and low pressure autoclave leaching after grinding to 105 microns. NSC Process This process is based on moderate pressure oxidation at 125-155C, catalysed with nitrogen species supplied from sodium nitrite, preceded by an ultrafine grind to 10 microns. Copper is recovered by conventional SX/EW. A small commercial circuit operated until the
For low copper oxide ores the cyclone overflow will be approximately 40% solids and will be directed to a leaching circuit comprising three 300m 3 agitated leach tanks in series. The ore will be dosed with sodium cyanide and limeto leach the cyanide soluble gold. To assist the leaching kinetics oxygen will be injected into each leach tank
Copper recovery using leach/solvent extraction/electrowinning technology 65 (Figure 2) and a catalytic amount of LIX 63, was introduced in 19657 and in March 1968 the first commercial copper L/SX/EW operation, the Bluebird plan of Ranchers

leaching, the process starts with crushing, grinding and a separation circuit followed by thickening. The slurry then enters vat leaching tanks and moves to solvent extraction through dewatering. Heap leaching, which is one of the most common leaching methods, starts with sprinkling a low concentration of sulfuric acid and water solution on a stockpile (leach pad) of low-grade ore. The liquid
