摘要： A mineral separation process includes wet-grinding the ore to liberation of minerals, oxidizing the slurry using air, hydrogen peroxide or other oxidants and floating the valuable minerals at a pH between about 9.0 and 10.0 with a xanthate as collector, and a combination of a polyamine and a sulfur containing species as depressants for arsenide minerals. This depressant suite effectively depresses the flotation of arsenide minerals with no effect on the flotation of the valuable minerals.

摘要： Novel thionocarbamate compounds having one or more substituents with five or more carbon atoms have been produced and evaluated as collectors used in froth flotation processes for the recovery of minerals. The amounts of minerals being recovered are greater as compared to the results obtained from using a conventional collector as a standard when using the novel thionocarbamates. Not only is the amount of materials recovered increased, i.e. enhanced yield, but also the novel thionocarbamate collectors have enhanced selectivity by rejecting iron to a greater extent than the standard so that the purity of the mineral being recovered is increased. A method of making the novel thionocarbamates is described using novel xanthates and amines, including novel amines. The advantage of the processes and methods is that the xanthates used to produce the novel thionocarbamates do not need to be pre-treated by being dried, purified, isolated, but rather the xanthates can be used in the form as produced.
摘要翻译：已经生产具有一个或多个具有五个或更多个碳原子的取代基的新型硫代氨基甲酸酯化合物，并将其评估为用于回收矿物质的泡沫浮选方法中的收集器。与使用新型硫代氨基甲酸酯时作为标准的常规收集器获得的结果相比，回收的矿物质的量更大。不仅回收的材料量增加，即提高产率，而且新型硫代氨基甲酸酯收集剂通过以比标准物更大的程度排出铁来提高选择性，使得回收的矿物质的纯度增加。使用新颖的黄原酸盐和胺（包括新的胺）来描述制备新型硫代氨基甲酸酯的方法。该方法和方法的优点是用于生产新型硫代氨基甲酸酯的黄原酸酯不需要通过干燥，纯化，分离来进行预处理，而是黄原酸酯可以以所生产的形式使用。
