Polymeric building materials based on flotation waste from flotation of copper ore and waste sulfur

摘要

The method of production of polymeric construction material from flotation waste originating from copper ore flotation and waste sulfur is described. The method includes mixing of 20-50% by weight of waste sulfur which is combined with 10-50% by weight of flotation waste from flotation of copper ore and 3-25% by weight of waste phosphogypsum as pH regulator. Finally, 10-40% by weight of mineral filler is added. The mixing occurs at a temperature of 130-150 degrees Celsius and the mixing lasts for about 30 minutes with rotational speed of an agitator of 20 rpm.
