The pretreatment of refractory gold ore is a complex chemical process. In addition to the oxidation of pyrite, some side reactions also occur. The phase changes of refractory gold ore before and after pretreatment are shown in Fig. 11. The main phases of refractory gold ore include quartz (SiO 2), pyrite (FeS 2), and dolomite (CaMg(CO 3) 2 ...

Plant design parameters for gold extraction, leach residence time and cyanide consumption are generally determined from standard bench-scale bottle roll or agitation leach tests.

Experience has shown how difficult it is to obtain information regarding laboratory-tests in connection with the gold ore chlorination process for the extraction of gold from its ores, and I therefore present the following method, somewhat in detail, for the benefit of those who may desire to pursue research work in this field..

Prospecting for gold can be a fun hobby, though it's a lot of work! You may be able to harvest gold flakes from rock if it contains gold among its minerals. The safest way to extract gold from rocks at home is to crush the rocks. However, you might use mercury to extract the gold if you're able to obtain some, though this is dangerous.

For the past 100 years, the key element in the processing of gold ore has been the cyanidation process.Over the years, steady improvements have occurred in equipment design; milling has evolved from stamp mills, through tube mills and ball mills to the large semiautogenous grinding (SAG) and fully autogenous grinding (FAG) circuits in modern gold plants.

For carbonaceous gold ore and its concentrates, gold extraction by direct cyanidation is usually low due to the known preg-robbing effect. The leaching behavior of a carbonaceous gold ore with a high content of dolomite in copper-ammonia-thiosulfate solutions was investigated. A gold extraction of 74% was achieved in a copper-ammonia ...
