摘要： A flotation device for mixing and aerating an ore-containing slurry, comprising a tank having a conical-shaped floor. A vertically positioned flotation assembly is located within the tank. The open bottom of the flotation assembly is shaped is positioned above the conical portion of the floor. The assembly has a middle section having a cage with spaced, vertical bars forming its outer circumference. A rotatable impeller is located within the middle section which draws slurry from the tank through the bottom section and into the middle section and thereafter through the cage and out of assembly. The impeller is attached to a rotatable shaft which is connected at its bottom portion to the upper side of the back plate to rotate the impeller in a plane normal to the shaft. A hollow, vertically situated tubular shaped upper section is located directly above the middle section through which the shaft passes. The upper section has an opening at its lower end which is blocked by the back plate of the impeller.

摘要： Hydrometallurgical techniques for the selective recovery of Zn, Mn and Pb in that order from sludges or various metallurgical residues can include leaching steps to extract the zinc and manganese; the steps of removing iron, aluminum and silica from the leaching solutions; and recovering manganese and zinc by precipitation. Mn can be precipitated from an initial leaching solution as well as a secondary leaching solution obtained by leaching the slurry of the initial leaching step. Various other waste streams can also be treated.

摘要： The invention concerns a method for eliminating bismuth from molten lead with magnesium and calcium, which consists in inputting magnesium and calcium in the form of lumps of two Mg-Ca alloys, one containing predominantly Mg, the other containing predominantly Ca, each having a Liquidus temperature lower than 650 °C, and preferably less than 600 °C. The Liquidus temperatures of the two alloys are preferably close to less than about 20 °C. A particularly efficient treatment is obtained with a Mg-Ca alloy close to the eutectic alloy at 16.2 wt. % of calcium and containing 12 to 25 % of calcium and a Ca-Mg alloy containing between 60 and 80 % of calcium. The invention enables fast elimination of bismuth and adjustment of the Ca/Mg ratio during treatment.

摘要： Any metal having a low α-ray emission, the metal being any one of tin, silver, copper, zinc, or indium, wherein an emission of an α-ray after heating the metal at 100° C. in an atmosphere for six hours is 0.002 cph/cm2 or less. Any metal of tin, silver, copper, zinc and indium each including lead as an impurity is dissolved to prepare a hydrosulfate aqueous solution of the metal and lead sulfate is precipitated and removed in the solution. The lead sulfate is precipitated in the hydrosulfate aqueous solution by adding a lead nitrate aqueous solution including lead having an α-ray emission of 10 cph/cm2 or less to the hydrosulfate aqueous solution, from which the lead sulfate has been removed, and, at the same time, the solution is circulated while removing the lead sulfate to electrowinning the metal using the hydrosulfate aqueous solution as an electrolytic solution.
