The Porphyry Copper Extraction Process Flowsheet Crushing Porphyry Copper Ores. Three stage crushing is illustrated in the flowsheet; however, it is possible and practical to eliminate the third stage by incorporating a rod mill in the grinding section. This is a very practical arrangement and often a necessity when handling wet, sticky ore.
LIX 64 alone was able to extract copper selectively from iron in the pH range 1.5-2.5, but with the disadvantage of slow rate of extraction. This was solved by the addition of a small amount of LIX 63. The mixture, LIX64N, for many years was the extractant of choice for commercial copper extraction from acidic leach solution (Szymanowski, 1993).
The ore, broken by drilling and blasting, is hoisted through the shaft and conveyed to the processing plant. In some cases, primary crushing takes place underground; in others, a ramp and trucks carry ore to the …

Before the beneficiation of copper ores, crushing and grinding are required. The bulk ores are crushed to about 12cm by a jaw crusher or a cone crusher. Then the crushed materials are sent to the …
The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ((CuFeS_2)) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper. ...
Copper can be extracted from non-sulfide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a …

Oxide ores are generally processed using hydrometallurgy. This process uses aqueous (water-based) solutions to extract and purify copper from copper oxide ores at ordinary temperatures, usually in three steps: heap leaching, …
The extraction of copper from copper ore involves crushing, grinding, flotation, smelting, and refining processes. Copper ore has numerous uses and applications, including electrical and electronics, construction and architecture, transportation, renewable energy, consumer goods, agriculture, health and medicine, …
Hence, this study has been focused to obtain optimum conditions for copper extraction from the crushing reject by studying the kinetics and mechanism of copper dissolution in sulfuric acid solutions. In addition, the actual particle size of the studied material is highly proper for a tank-leaching operation. Meanwhile, noting the market …
