Apr 01, 2012· Roy et al. usedgoldmilltailingsto makebricksby mixing them with OPC, black cotton soils or red soils. The OPC-tailings brickswere just cured by immersing them in water but the soil-tailings brickswere sun-dried and then fired at high temperatures (750, 850, and 950 °C).

Similar study was carried out by Yonggang et al. (2011) on firedbricksby usinggoldmilltailingsand clay. The sequence of pretreatment, mixing, ageing moulding, drying, sintering and ...

Oct 19, 2015·Bricksmade fromtailingscost more than conventionalbricksbecause of the higher quantity of cement used, but themanufacturingprocess consumes less water. Overall, the results indicated thatgoldminetailingshave a high potential to substitute for the natural materials currently used in brickmaking.

Minetailings(MT) have been used in previous studies as substitute construction material to recycle waste products, especially in hollow blocks andbricksproduction and as masonry mortar. This study investigated theuseof Philex copper-goldminetailings(PCGMT) in roller compacted concrete (RCC) production, a mining waste material consisting of finely grinded siliceous particles was ...
