摘要： This application pertains to methods of recovering metals from metal sulfides that involve contacting the metal sulfide with an acidic sulfate solution containing ferric sulfate and a reagent that has a thiocarbonyl functional group, wherein the concentration of reagent in the acidic sulfate solution is sufficient to increase the rate of metal ion extraction relative to an acidic sulfate solution that does not contain the reagent, to produce a pregnant solution containing the metal ions.

摘要： The invention relates to a green carbon paste comprising electrically calcined anthracite coal (ECA) and a green binder comprising glucose, glycerol and a minimum amount of epoxy resin which is used as a tamping/ramming paste in lining cathodes in an aluminium electrolysis cell. The binder is substantially devoid of volatile organic compounds and thereby the paste is environment friendly.

摘要： The cathode assembly of a reduction cell for aluminium production contains a metal pot with a bottom, bearing members covering the longitudinal and end walls and the bottom of the pot, with lining enclosed therein and cathode blocks with cathode rods forming the cathode of the reduction cell. On the longitudinal and end walls of the metal pot in the gaps between the bearing members there are fixed plate ribs and/or finger ribs with a developed structure for heat removal, with a belt made of composite material for steady heat removal installed in the upper part of the longitudinal and end walls of the metal pot. The cooling effect is achieved by a convective air flow caused by the lifting force resulting from the air heating in the space between the ribs at the melt level and the resulting temperature difference along the height of the cathode casing walls.
