PUTRAJAYA The government is planning to revive the tin mining industry in Malaysia back to its golden age as achieved decades ago when it was the largest tin producer in the world
Tin Tin ore continued to be mined but not as much as in the past glorious years of the 70s and 80s when Malaysia was the world’s largest tin ore producer High grade deposits have inevitably been exhausted following decades of tin mining
Until the late 1970s Malaysia was the worlds premier producer of tin supplying some 40 per cent of the worlds tin In the 80’s due to the exhaustion of tin and a fall in tin prices Malaysia was no longer a premier tin producer However bauxite and copper continued to contribute to the mining
Vein and disseminated tin deposits are mined by the same methods used in hardrock mining of other nonferrous ores such as zinc The ore is broken by drilling and blasting transported to a concentrator where it is crushed and ground and then concentrated primarily by gravity methods
They are mined by one of several surfacemining methods principally gravel pumping dredging and to a smaller extent openpit mining A large proportion of tin ore is mined by gravel Tin processing Tin processing Mining and concentrating Vein deposits such as those in Bolivia and the United Kingdom usually occur in granite formations and are recovered by conventional underground hardrock mining
