Zinc and nickel removal in simulated limestone treatment of
Abstract. Mining influenced water (MIW) is often characterized by low pH (acid mine drainage) and high dissolved metal concentrations. Treatment of MIW is often To minimize waste extraction activities, hyperspectral remote sensing imagery utilized to identify the purest form of calcite in the examination area.

Calcite is one of the most abundant simple salts in the earth’s surface and in sedimentary rocks; it occurs in the form of armours and skeletal frames of marine creatures. It is the prime constituent of limestone, chalk etc. In igneous rocks, calcites are present in the form of fine-to-coarse grains.An Overview of Calcite Recovery by Flotation Springer

Comparative stability analyses of traditional and selective
The stability and productivity concerning a modification on the traditional room and pillar for a new selective technique at the Portuguese Panasqueira Mine have been described. The traditional room-and-pillar stoping uses 5.0-m wide rooms with 3.0 m ×3.0 m pillars, while the selective room-and-pillar mining technique consists in stoping This paper investigates possibilities for the selective mining of kukersite oil shale.
