• Extraction Of Tin From Its Ores

    EPA1 Extraction of tin from its ores Google Patents. A process for the direct recovery of tin values, as organo hydrocarbyl tin compounds, from reduced but unrefined tin ores and ore slags is described, wherein the ore or slag is reacted directly with a hydrocarbyl halide to form an organo hydrocarbyl tin compound which can then easily be separated from the tindepleted ore or slag residue.
