What is the collector commonly used in the gold concentrator?
The collectors commonly used in gold concentrators include xanthate, black drug, butylammonium black drug, neutral oil (such as diesel oil), hydroxamic acid and its salts, mercaptobenzothiazole (MBT), Z-200, aminoalcohol yellow drug, etc. sometimes non-polar oil collectors are used as auxiliary collectors to flotation natural gold. The latest collectors are butyl xanthate ethyl formate, Y-89, thiocarbamate, thiocarbonyl carbamate, ethyl thiocarbamate, alkoxy or phenoxyalkylthiocarbamate, thiourea, amines, dialkyl or diaryl thiophosphate, thiophosphonate, imidazole, aminothiophene, thiophosphite, thiocarbamate, etc.
What is the commonly used medicament system of gold flotation?
Gold flotation can be used as collectors such as xanthate, cuphol, thiazole, benzhydrin and butylhydrin, among which xanthate is widely used, and terpineol oil can be used as foaming agent. The mixture of high-grade xanthate and low-grade xanthate in a certain proportion is better than the single out one. It can improve the recovery rate and flotation speed, reduce the dosage of high-grade xanthate, reduce the cost of reagents, reduce the flocculation degree of fine ore particles and improve the selectivity of the process. It is very important for the ore to be mixed with sulfide.
What is the foaming agent commonly used in the gold concentrator?
The commonly used frother in the gold concentrator are No.2 oil, camphor oil, dipyridine, a-section acid, etc. Among them, No. 2 oil is the most widely used.
What are the commonly used inhibitors in gold concentrators?
The metal mineral inhibitors commonly used in gold concentrators are lime, cyanide, sodium sulfide and dichromate. Gangue mineral inhibitors include sodium silicate, starch, dextrin, etc.
Lime is not only a common medium regulator, but also an agglomeration agent of slime and an effective inhibitor of pyrite, and it also has a certain inhibition effect on gold. Slurry pump manufacturer
Sodium silicate, starch and dextrin are commonly used gangue inhibitors for auriferous quartz vein ores, which can improve the quality of gold concentrate. Cyanide is a common inhibitor of pyrite, zinc sulfide and various copper sulfide minerals. When it is used, it is often added with lime or zinc sulfate, with good effect. However, cyanide not only has a strong inhibition on gold, but also dissolves precious metals such as gold and silver, so it is better not to use cyanide as an inhibitor in flotation of gold bearing polymetallic ores.
