2.1 Materials The starting materials were the magnesite tailings from Dashiqiao of Liaoning province (particle size<40 mm), with MgO content of 46.56% (mass fraction). Reagent grade potassium dihydrogen phosphate (KH2PO4) and ammonium carbonate((NH4)2CO3), and a type of soluble magnesium salt were used as additivesA new method is presented here for differentiating magnesite from dolomite in crushed materials. This method is based on the essentially different temperatures at which these minerals undergo thermal decomposition. The resulting lowly birefringent periclase is easily distinguished microscopically from the highly birefringent dolomite.

Due to the metal tolerance nature of these microbes could be useful to study and use on reclamation of various metal contaminated soils. Hence, the prime intention of this work was to isolate the indigenous metal tolerant microbes from magnesite and bauxite mine tailings. 2. Materials and methods2.1. Study areaThe recovery of magnesite ore from the blasted earth is about 7%, and after recovery of magnesite ore, the remnant earth materials, known as magnesite mine tailings (MMT), are open landfilled (Indian Minerals Yearbook - Magnesite 2018 ). However, due to the large-scale magnesite exploitation, an enormous amount of MMT is inevitably generated.
