With the rising gold prices in recent years, it further stimulated the rapid development of gold industry. As the exhaustion of high-grade gold ore, researching on middle-low grade and refractory gold ore and strengthen the traditional gold mining process undoubtedly have become the main trend in global gold beneficiation industry.

The EU standards are more recent (1998), complete and strict than the WHO standards (1993). Some examples are: - Bromate (Br): Not mentioned by the WHO, 0.01 mg/l guideline in the EU standards. - Manganese (Mn): Guideline reduced from 0.5 to 0.05 mg/l. - Cyanide …
Apr 20, 2003 Description: Limas are tropical beans named after Lima, the capital city of Peru. In the U.S. we grow large, white lima beans selected especially because they contain very small amounts of the poison cyanide. Fact: The small red lima beans that are grown in Asia contain 20 to 30 times more cyanide than the white varieties.
An electroplater needs to reduce 5-8 ppm cyanide in a 1,000 gallon per hour waste stream to less than 1 ppm. The raw water is at pH 9.6. Jar tests determined the cyanide concentration could be reduced to the discharge limit in just ten minutes by using CAIROX potassium permanganate. Over 92% cyanide removal was observed.
