A process in which ores or converter slags are ground and firstly have added thereto benzotriazole or alkyl benzotriazole as an activator and secondly one or more collectors selected from the group consisting of xanthates, dithiophosphates, thiocarbamate esters, dithiocarbamates, mercaptans and dixanthogens and further, if desired, a promoter such as kerosene, light oil ...
· Base metals such as , lead, and zinc are mainly extracted from sulfide ores. Mostly these base metals tend to exist together in an . process is widely used to separate these minerals in sulfide ores . A wide range of chemical reagents are used in the process to separate the different minerals.
Froth is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
cells, a new type of has recently been developed that works under the fluidized bed principle. With this new cell type, it has been possible to obtain recoveries up to 90% Cu and 89% Mo when a miner al has been in the range of 600 µm 150 µm.
Oxide ores in subdivided form may be concentrated in a separation process by slurrying said ores in an aqueous solution of a reagent followed by generating gas bubbles in the slurry to float the oxide and recovering the concentrated oxide from the surface of the slurry, wherein the reagent is a quaternary hydrocarbyl ammonium or phosphonium ...
