Post Prominer (Shanghai) Mining Technology Odpowiedz z cytatem
Until researchers come up with a more efficient and cost effective method of extraction, it looks like it will continue to remain the most popular gold processing plant method for the foreseeable future.The hydrometallurgical extraction of gold from ores, concentrates, and tailings in a cost effective and environmentally safe manner offers an interesting challenge. Conventional gold mining operations rely heavily on cyanide leaching as the predominant method for recovering gold from ores and concentrates. Cyanide has been the leach reagent of choice in gold mining because of its high gold recoveries, robustness and relatively low cost. As a result, over 76% of all gold extracted worldwide is produced by hydrometallurgical extraction with the use of cyanide.
The gold mining sector uses approximately 66,000 tons of sodium cyanide annually worldwide. The use and subsequent disposal of cyanide, Rare Earth Minerals Processing Plant significant safety and environmental challenges. As a result, the safety, environmental and associated permitting issues have been a critical driver for the industry to evaluate effective alternatives.
There are a number of alternatives that have been tried by the industry; thiosulfate, thiourea, various types of halides and so on. Although new processes are being proposed on a regular basis, there have in fact been no dramatic changes in the metallurgical techniques for gold extraction since the introduction of the cyanide process
