The invention provides method to recover, by means of froth flotation, a desired metal value from a feedstock containing it. In a comminution step, the feedstock is comminuted using comminuting media of an iron and chrome steel alloy comprising from 12% to 30% chrome. In a conditioning step, the feedstock material is contacted with thiourea and/or oxalic acid as primary flotation reagents.

Check if tailing occurs with all peaks or only with certain analyte classes or individual ions (this will help identify if secondary interactions are causing tailing). For unwanted hydrophobic interactions, use a more hydrophilic column or use an organic solvent additive to eluent (check complete system compatibility). If metal

Sep 01, 2018· The recovery vs. active materials content data obtained without kerosene shows a comparable separation performance with those obtained at an excess kerosene dosage (100 μL). In terms of active material contents in final tailing product, the use of kerosene increases the amount of active materials in tailings at an expense of the recovery.
A concentrate obtained from mining tailings containing mainly cassiterite and columbotantalite was reduced for the production of tin metal. The compounds CaCO3, Na2CO3, K2CO3, and borax were used as fluxes in the pyrometallurgical reduction smelting process, and graphite was employed as the reducing agent. The greatest recovery of Sn (>95%) was obtained when using CaCO3 as the flux; the purity ...

Secondary recovery by water injection increases the amount of oil recovered over primary production, but may still leave more than 80% of oil in the reservoir. To recover more oil, gas (CO2, nitrogen [N 2] and methane) may be injected. The process of recovering oil by injecting gas is known as tertiary recovery or enhanced oil recovery (EOR).
