含贵金属矿 渣浆泵石浮选药剂
28选金厂常用的捕收剂是什么?
    选金厂 常用的捕收剂有黄药、黑药、丁铵黑药、中性油(例如柴油)、羟肟酸及其盐、巯基苯并噻唑(MBT)、 Z-200、 氨醇黄药等,有时用非极性油类捕收剂作辅助捕收剂浮选自然金。最新研究的捕收剂有丁基黄原酸甲酸乙酯、Y-89、硫代氨基甲酸盐类、硫羰氨基甲酸酯、乙硫氨酯、烷氧基或苯氧基烷基硫羰氨基甲酸酯、硫脲、胺类、二烃基或者二芳基一硫代磷酸酯、一硫代膦酸酯、咪唑、氨基噻吩、一硫代亚磷酸、 硫代氨基甲酸盐类等。
29金浮选常用的药剂制度是什么?
金的浮选可用黄药、碗醇、噻唑、苯股黑药及丁基铰黑药等作捕收剂,其中以黄药应用较广,起泡剂可用松醇油等。高级黄药与低级此药按一定比例混合使用,比单出采用中一种为好,它可提高回收率和浮选速度,减少高级黄药用量,降低药剂费用,并可降低微细矿粒的絮凝程度,改善过程的选择性。混合用药对矿石中含有难选硫化物时显得特别重要。
30选金厂常用的起泡剂是什么?
    选金厂常用的起泡剂有2号油、樟油、重毗啶、甲段酸等。 其中以2号油应用最广泛。
31选金厂常用的抑制剂是什么?
    选金厂常用的金属矿物抑制剂有石灰、氰化物、硫化钠、重铬酸盐。脉石矿物抑制剂有水玻璃、淀粉、糊精等。
    石灰是一种常用的介质调整剂,又是矿泥的团聚剂和黄铁矿的有效抑制剂,并且对金也有一定的抑制作用。渣浆泵厂家
    硅酸钠、淀粉、糊精是含金石英脉矿石常用的脉石抑制剂,用于精选作业,可提高金精矿质量。氰化物是黄铁矿、硫化锌及各种硫化铜矿物常用的抑制剂,使用时,常与石灰或硫酸锌一起添加,效果很好。但氰化物不仅对金有强烈抑制作用,还能溶解金银等贵金属,所以在浮选含金的多金属矿,最好不用氰化物作抑制剂。

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.
