摘要： The present invention, therefore, provides stage crushing method for recovering precious metals from slag produced by a coal burning furnace or boiler comprising: a plurality of crushing steps, wherein each crushing step produces slag particles having successively smaller particle diameter sizes, said crushing steps continued until a final desired particle diameter sized is obtained; wherein each of said crushing steps is followed by suspending said crushed slag particles in a liquid medium to form a slurry of light-weight particles and heavy-weight particles and allowing the crushed slag particles within the slurry to separate, based on weight of the particles, thereby forming a light-weight particle population and a heavy-weight particle population; wherein each suspending step is followed by removing said light-weight particles from said slurry, such that said slurry consists of substantially heavy-weight particles; and collecting said heavy-weight particles.

摘要： The invention relates to an improvement in a method for recovering metal values from copper-containing and/or precious-metal containing materials which also contain antimony and/or bismuth in such high quantities as to render working-up of the materials with conventional metallurgical processes difficult or impossible. In accordance with the improvement, the material is subjected to a chlorination volatilization process in a manner to bring the antimony and/or bismuth content of the material to a predetermined low level acceptable for the continued working-up of the material in conventional process stages, while maintaining the metal values of the material in a substantially unaffected form. The volatilization process is best carried out at temperatures of between 450° C and 750° C, preferably between 550° C and 650° C.
The chlorination process can be carried out on materials included in the group: sulphidic or oxidic-ore concentrates, matte, speiss, oxidic and metallic intermediate products. In certain cases it is convenient to convert the material to another form within the group, for example the matte, prior to carrying out the chlorination process.

摘要： The present invention provides a process for recovering valuable metals from precious metal smelting slag, comprising: smelting the precious metal smelting slag and a flux in a top-blown rotary furnace to produce a lead-bismuth alloy, wherein the precious metal smelting slag comprises Au, Ag, Bi and Pb; electrolyzing the lead-bismuth alloy at a current density ranging from 60 to 110 A/m2 to obtain lead cathode and lead anode slime; refining the lead anode slime to produce bismuth and silver-zinc crust, and extracting gold and silver separately from the silver-zinc crust. Through utilizing a top-blown rotary furnace as the smelting apparatus and adjusting the ratio of the flux, the present invention enriches the valuable metals gold, silver, bismuth, lead or the like to lead-bismuth alloy, ensures lower contents of gold, silver, bismuth and lead in the reducing slag and thereby increases the comprehensive recovery rates of gold, silver, bismuth and lead from the precious metal smelting slag.

摘要： A method for recovering platinum group elements comprises charging an oxide raw material entraining platinum group elements, copper oxide, solid carbonaceous reducing agent and flux into a closed electric furnace equipped with at least one electrode for heating material and a roof for substantially shielding material charged into the furnace from the exterior atmosphere. The charged material is melted and reduced to form a layer of molten metal under a molten slag layer and enrich platinum group elements in this molten metal. The oxide raw material, copper oxide, solid carbonaceous reducing agent and flux are prepared as powdery or particulate materials, premixed and then charged into the electric furnace. The heat-melted material in the furnace is allowed to stand at a temperature of 1200° to 1500° C. for at least 5 hours, with the molten metal containing platinum group elements then being discharged outside the furnace.

摘要： A method is disclosed for treating dore slag resulting from smelting of a dore furnace charge, by grinding such slag and then subjecting the obtained pulp to froth flotation in the presence of a suitable frother and collector to produce a precious metals concentrate which is then filtered and returned to the dore furnace with the next charge. The tails from the froth flotation may then be finely ground and subjected to several additional flotation stages to improve recovery of the precious metals, and the entire operation is preferably carried out as a closed loop process so that only the tailings from the rougher flotation are removed and shipped to the smelter.
