tin powder recovery from chromite ore

Extraction of tin from its ores

A process for the direct recovery of tin, as an organo hydrocarbyl tin compound, from reduced but unrefined tin ores and ore slags is described, wherein the ore is reacted directly with a hydrocarbyl halide to form an organo hydrocarbyl tin compound which can then easily be removed and separated from the tin-depleted ore residue.
