Optimization of Reductive Leaching of Tidar Cobalt Ore Using Taguchi Method
Reductive leaching was used to dissolve metals, especially cobalt, present in Fars Tidar mine,. In this paper, cobalt ore was leached with sulphuric acid in the presence of phenol to determine the effects of various factors on leaching. These factors included temperature, acid concentration, time, phenol content, pulp density, and interaction between some of the parameters. The results indicate...

متن کاملCobalt-catalyzed reductive coupling of activated alkenes with alkynes.
Cobalt complex/Zn systems effectively catalyze the reductive coupling of activated alkenes with alkynes in the presence of water to give substituted alkenes with very high regio- and stereoselectivity in excellent yields. While the intermolecular reaction of acrylates, acrylonitriles, and vinyl sulfones with alkynes takes place in the presence of CoI2(PPh3)2/Zn, the reaction of enones and enals...
متن کاملAbiotic reductive dechlorination of chlorinated ethylenes by iron-bearing phyllosilicates.
Abiotic reductive dechlorination of chlorinated ethylenes (tetrachloroethylene (PCE), trichloroethylene (TCE), cis-dichloroethylene (c-DCE), and vinylchloride (VC)) by iron-bearing phyllosilicates (biotite, vermiculite, and montmorillonite) was characterized to obtain better understanding of the behavior of these contaminants in systems undergoing remediation by natural attenuation and redox ma...
متن کاملCobalt-catalyzed reductive Mannich reactions of 4-acryloylmorpholine with N-tosyl aldimines.
Using cobalt catalysis, diethylzinc promotes the conjugate reduction of 4-acryloylmorpholine to produce the corresponding ethylzinc enolate, which reacts with N-tosyl aldimines to afford beta-aminoamides.
