Comprises 16 papers covering the geology, ore genesis, beneficiation and extractive metallurgy of complex tin ores., Comprises 16 papers covering the geology, ore genesis, beneficiation and extractive metallurgy of complex tin ores.

Aspects of beneficiation considered in the 16 papers include: applied mineralogy of alluvial tin; alluvial tailings; improved spiral technology; dry separation; energy consumption and transport and processing costs in Malaysian gravel pump mines; ore treatment at P.T. Koba Tin; beneficiation at Bidor Malaya Tin; gravity concentrating trays; by-product recovery; separation of columbite-tantalite from ilmenite; tin liberation from limonitic boulders; heavy medium cyclones; Bolivian treatment practices; tungsten recovery by caustic leaching; arsenic removal from roaster dust; and pyrometallurgy and hydrometallurgy of tin-tantalum-antimony at Greenbushes, Australia. Discussions of each paper, and the panel discussion, are also included., Aspects of beneficiation considered in the 16 papers include: applied mineralogy of alluvial tin; alluvial tailings; improved spiral technology; dry separation; energy consumption and transport and processing costs in Malaysian gravel pump mines; ore treatment at P.T.
