Table chemical composition of mine tailings (%)
According to domestic data and determination of tailings performance, tailings can be used for refractory clay, construction, cement ingredients, ceramic tiles, etc. For example, Shanxi tailings contain Al 2 O 3 57.48%, Fe 2 O 3 1.61%, CaO 0.13%, and the refractoriness is greater than 1799 ° C, which is in line with the high alumina bauxite refractory standard. Guangxi Pingguo bauxite tailings have high iron content and can also be used as building bricks. After molding, they can reach 150kg/cm 2 and the strength is more than double that of ordinary bricks.

Comprehensive utilization of bauxite tailings
After dressing bauxite, tailings output part, with its composition and yield of ore beneficiation methods and ingredients vary. Generally, when the ore contains Al 2 O 3 in the range of 50% to 60%, after tailing, the tailings production is about 35% to 38%; the main components in the tailings are A l2 O 3 and SiO 2 , a small amount. There are oxides of calcium, magnesium , iron and titanium . The tailings composition of ore after mineral processing in some key mines in China is shown in Table 1. Seen from the table, the tailings component meet the requirements of the raw material bauxite metallurgical YB2212-73 standards issued by the Ministry of two products (B) a.
