In most cases, the thin-layer process was used where crushed ores (80% −0.5 in) were stacked in heaps of 3–8 m height after agglomeration and sprayed at flow rates of 6–40 L·hour −1 ·m −2 with 15–90 days duration for copper oxides and 10–18 months for sulfides. Of note, 80%–85% copper extraction was commonly achieved.

SUMMARY The leaching and SX/EW technique has been rapidly developing world-wide tech-nology for copper production in recent years. For many years this technology was re-lated mostly to oxide copper ores, but recently we can observe a growing interest in application of this method also for sulphide ores, by-products and concentrates proc-essing. The success could not be …
silver and copper from these ores. The processes include heap leaching, agitation leaching and flotation. Geometallurgy is used to classify the various types of ore found in this complex ore body and to determine the optimum processing route for each ore type. Examples of the ore classification system are given.

The first step, mineral processing, is to liberate the copper minerals and remove waste constituents—such as alumina, limestone, pyrite, and silica—so that the copper minerals and other nonferrous minerals of value are concentrated into a product containing between 20 and 30 percent copper. The second step, involving either smelting or leaching, removes a large …
