2 INTRODUCTION A typical flowsheet[1,5,8] that incorporates the SART process to recover copper from gold/copper ores after cyanidation, is illustrated in Figure 1 as "Current Flowsheet". This type of process was developed to allow the economical treatment of ores with a high cyanidesoluble copper content

Underground leaching is a filtration process and is based on solidliquid chemical reactions. In the underground leaching of permeable ore bodies, the deposit is mined by a series of wells arranged in series, polygons, or rings. The solvent is introduced into the wells, filters through the stratum, and leaches the useful components.

The Case for Glycine Heap Leaching

The Case for Glycine Heap Leaching

Project Target 2 – Gold ore with nuisance copper. Gold ores with elevated or 'nuisance' copper levels are difficult to process by conventional cyanide heap leaching, as the copper causes high cyanide consumption. As well as the direct cyanide cost, this increases the cost of detoxifying effluent solutions.

When processing copper through heap leaching, vast quantities of ore and overburden overburdenSoil and rocks that have been moved out of the way to get to ore are called "overburden." In areas where there are high concentrations of radionuclides in the rock, overburden may have some enhanced radioactivity, but not enough to mine and process.

High Pressure Acid Leach

High Pressure Acid Leach

High Pressure Acid Leach (HPAL) is a process used to extract nickel and cobalt from laterite ore bodies. The HPAL process utilizes elevated temperatures (roughly 255 degrees Celsius), elevated pressures (roughly 50 bar or 725 psi), and sulfuric acid to separate nickel and cobalt from the laterite ore.

During insitu leaching, rather than removing soil and rock to reach copper deposits, acids are injected into ore bodies via wells. The PLS is captured in production wells and pumped to a leach plant where the copper is later recovered. High levels of TENORM have been found in the PLS of two insitu leach operations in Arizona.
