  • Use of gold mill tailings in making bricks: a feasibility

    Mill tailings dumps at Kolar Gold Fields, Karnataka, are creating environmental problems One of the solutions to these problems is to use the mill tailings for some useful purpose This study examined the possibility of making bricks from the mill tailings with some additives inRoy et al used gold tailings, ordinary Portland cement, black cotton soils, and red soils as raw materials to prepare cementtailings bricks and soiltailings bricks They found that soiltailings(PDF) Use of gold mill tailings in making bricks: ABricks made from tailings cost more than conventional bricks because of the higher quantity of cement used, but the manufacturing process consumes less water Overall, the results indicated that gold mine tailings have a high potential to substitute for the natural materials currently used inThe viability of using the Witwatersrand gold mine

  • The viability of using the Witwatersrand gold mine

    Gold mine tailings have also been used to produce autoclaved calcium silicate bricks (Jain et al, 1983) The bricks are cured under saturated steam and in the process, lime reacts with silica grains to form a cementing material consisting of calcium silicate hydrateMine tailings (MT) have been used in previous studies as substitute construction material to recycle waste products, especially in hollow blocks and bricks production and as masonry mortarUtilizing Mine Tailings as Substitute ConstructionIn Arequipa Peru, tailings produced from the gold cyanidation process are deposited in tailings dumps This accumulation creates the need for large spaces, high maintenance costs, and a negative impact on the environment The present study aims to develop a process for reusing gold mine tailings as a raw material for the manufacture of bricksDesign and implementation of an alternative process for
