Recovery of Ultra-Fine Iron Ore from Iron Ore Tailings

Sep 14 2017 · Many attempts has been taken for further utilisation of the tailings and slimes through different routes i.e. beneficiation agglomeration etc. Though the slimes and tailings contain huge ultra fines conventional beneficiation methods many not be much effective for handling because of particle size limitations. Physicochemical method i.e. selective flocculation is a process for handling the

OPTIMIZATION OF COMMINUTION CIRCUIT THROUGHPUT AND

Jan 01 2003 · Abstract. The goal of this project is to improve energy efficiency of industrial crushing and grinding operations (comminution). Mathematical models of the comminution process are being used to study methods for optimizing he product size distribution so that the amount of excessively fine material produced can be minimized.

Selenium Recovery in Precious Metal Technology

Selenium is mostly extracted from copper anode slimes because the selenium-rich ores are too rare to be mined with profit. When copper anode slimes are processed in a precious metal plant the first step is to remove copper by pressure leach in an autoclave. The anode slime

Biobeneficiation of Iron Oressapub

Iron ore fines and slimes present in tailing dams can be efficiently agglomerated and stabilized using native microorganisms from an environmental angle. Also such bioprocess would pave the way for recovery of valuable minerals from wastes and for reharvesting and recirculation of process water.

GOLD AND SILVERSuperfund Records Collections

Cyanidation leaching is the primary means of recovery of fine gold and silver. In this process solutions of sodium or potassium cyanide are brought into contact with an ore which may or may not have required extensive preparation prior to leaching. Gold and silver are dissolved by cyanide in solutions of high pH in the presence of oxygen.
