本文研究了用硫羰酯作捕收剂时水玻璃对黄铜矿和方铅矿浮选行为的影响以及铜铅人工混合矿的分离。结果表明用硫羰酯作捕收剂时!水玻璃对方铅矿有足够的抑制效果,而用丁基黄药时,仅有轻微的抑制性;硫羰酯—水玻璃有可能是铜铅分离的良好药方。通过吸附密度测定,研究了水玻璃对方铅矿的抑制机理。水玻璃的抑制作用与它阻止或降低捕收剂的吸附有关,它能完全阻止硫羰酯在方铅矿上的吸附,而不能完全阻止丁基黄药的吸附,表明捕收剂和抑制剂之间存在着弱一弱,强一强匹配现象。本文研究了用硫羰酯作捕收剂时水玻璃对黄铜矿和方铅矿浮选行为的影响以及铜铅人工混合矿的分离。结果表明用硫羰酯作捕收剂时,水玻璃对方铅矿有足够的抑制效果,而用丁基黄药时,仅有轻微的抑制性;硫羰酯—水玻璃有可能是铜铅分离的良好药方。通过吸附密度测定,研究了水玻璃对方铅矿的抑制机理。水玻璃的抑制作用与它阻止或降低捕收剂的吸附有关,它能完全阻止硫羰酯在方铅矿上的吸附,而不能完全阻止丁基黄药的吸附,表明捕收剂和抑制剂之间存在着弱一弱,强一强匹配现象。
In this paper, the influence of sodium silicate on the flotation behavior of chalcopyrite and galena with the use of thioester as a collector and the separation of copper-lead man-made mixed ore are studied. The results showed that when using thioester as a collector, waterglass had sufficient inhibitory effect on galenite, whereas butyl xanthate showed only slight inhibition. Thiocarbonate-waterglass was likely to be a copper-lead separator Good prescription. The adsorption mechanism of waterglass to galena was studied by adsorption density measurement. The inhibition of water glass is related to its ability to prevent or reduce the adsorption of collectors. It completely prevents the adsorption of thioester on galena and does not completely prevent the adsorption of butyl xanthate, indicating that collectors and inhibitors There is weak and weak, strong and strong match phenomenon.
