Rebellious Tin Ore Processing with New Agents for Nonferrous and Noble Metal Recovery

Аннотация

The occurrence form of sodium dibutyl dithiocarbamate on chalcopyrite is defined by IR spectroscopy. A stable compound of lead dibutyl dithiocarbamate forms on galenite. Fat acids of tall oil are adsorbed at the surface of cassiterite as chemically adsorbed oleate and physically adsorbed calcium dioleate. Sodium oleate adsorption at quartz surface is unfound in the mineral spectra after contact with fat acids, which proves selectivity of this agent relative to cassiterite. Applicability of 1,3,5-triazine-2,4,6-triamine agent to flotation of silver-bearing minerals is studied. The output of ultrasonic treatment aimed to remove slime material which deteriorates gravity separation of tin tailings at Solnechny Mining and Processing Plant is described.
