  3. Abstract:
  4. Site visits of selected factories and mines show large amounts of coal were collected as spoil and waste outside these locations due to un-efficiency of coal exploiting technology from mined material. The coal content of these waste materials is about 60%. In this work, we propose a method to be used for complete consumption of these materials in industry. In some samples, volume and weight of spoils could be decreased by half. This review also shows that aluminum oxide in industrial and minerals spoils are high, in some samples up to 25%. We suggest some remedies, e.g. we can use ashes produced by complete combustion of coal for production of aluminum hydroxide thus making it economical. More important is that by this method we can decrease environmental danger (hazards) of transferring elements and hazardous compounds, significantly (by preventing their transfer to the environment). Acidity of water drainage that generally contains high amount of heavy metals and hazardous waste are among important problems in coal Industries
