| titleOfInvention | Improvements in or relating to froth flotation concentration of minerals |
| abstract | In concentrating ores by the flotation process a compound of arsenic is added to the pulp as a differentiating flotation agent. A compound of arsenic with an alkali metal, preferably also containing sulphur, e.g. sodium thioarsenate, may be used or arsenious oxide or sulphide may be added in conjunction with an alkali or a sulphide hydrosulphide or polysulphide of an alkaline base, e.g. an alkali metal base, an alkaline-earth base or ammonia. The flotation reagent is preferably added in the grinding mill. Examples are given of the separation of lead and zinc sulphides in which the lead is first floated by means of an arsenic compound and cresylic acid or cresol and xanthate, the residue being treated with copper sulphate and frothing reagents, e.g. creosote and xanthate, to float the zinc. |
