Abstract: A method of removing gallium from tin, lead or tin-lead alloy in which the molten metal containing gallium is treated with a molten flux of alkali metal hydroxide, alkali metal carbonate or a mixture of such constituents where the alkali metal is lithium, sodium, potassium or a mixture of these. Preferably the metal and flux are stirred together, then separated, and the flux dissolved in water and gallium recovered from the solution by electrolysis.

Abstract: A process is disclosed for the suspension or flash smelting of finely-divided oxide and sulfide ores and concentrates, a process in which a suspension of a finely-divided raw material in preheated air or oxygen is fed downwards at the reaction temperature or a higher temperature in a reaction zone formed together by the suspension and the smelt underneath in order to oxidize and partially smelt the suspension raw material, whereafter the oxidized raw material is partially sulfidized and the suspension flow is made to change its direction perpendicularly to the side so that the bulk of raw material in the suspension flow impinges towards the surface of the accumulated smelt in the main smelt reaction zone under the suspension reaction zone, and the remaining suspension flow is fed to a zone which has a rising flow, where the suspension is possible after-sulfidized and cooled and the solids to be returned to the suspension reaction zone are separated from the residual suspension flow. The suspension flow portion not impinging against the smelt surface in the main smelt reaction zone is fed into a secondary reaction zone wherein it is allowed to, at least, partially dissolve in the smelt before the undissolved residual suspension is fed into the rising-flow zone so as not to affect a smelt settling zone communicating with the main and secondary smelt reaction zones and in which slag is separated from matte and metal.

Abstract: 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.
