Detailed introduction

extraction of metal from the ore cassiterite involves ...Tin is obtained by reducing the ore cassiterite with coal in a reverberatory furnace; Limestone is added to produce a slag with the impurities, which can be removed. Crude tin so obtained is contaminated with iron, lead and other metals. It is, therefore, remelted on an inclined furnace. The process is .Determination of tin as stannite-kesterite and cassiterite ...Jun 01, 1975· The sodium nitrate-acetic acid method is effective for the determination of tin present as stannite-kesterite and as cassiterite in an ore.EPA1 - Extraction of tin from its ores - Google PatentsA 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 tin-depleted ore or slag residue.
