摘要： Apparatus is providing featuring a synthetic bead having a solid-phase body with a surface, and being configured with a predetermined electric charge so as to respond to a corresponding predetermined electric field; and a plurality of molecules attached to at least part of the surface, the molecules comprising a functional group selected for attracting and attaching one or more mineral particles of interest to the molecules. Some combination of the solid-phase body or the surface may be configured from a polymer. The polymer may be polyethylenimine. The polyethylenimine may be engineered or configured to be highly charged so as to be used to collect the mineral particles of interest and then manipulated through and by the corresponding predetermined electric field.

摘要： A method of using the synergy of multiple depressants to improve the depression of iron sulphide without compromising the recovery of the valuable sulphide minerals in the flotation of non-ferrous metal sulphides, while reducing or eliminating the use of environmentally problematic chemicals such as polyamines. The method has significant economic and environmental benefits. The multiple depressants comprise at least one organic polymer, at least one sulphur-containing compound and/or at least one nitrogen-containing organic compound.
