Heavy metal pollution caused by small-scale metal ore

Although metal ore mining activities are well known as an important source of heavy metals, soil pollution caused by small-scale mining activities has long been overlooked. This study investigated the pollution of surface soils in an area surrounding a recently abandoned small-scale polymetallic mining district in Guangdong province of south China.

Environmental Risks of Mining

There is no ore dust or direct ore exposure to the environment and a lower consumption of water is needed in the mining process (International Atomic Energy Agency [IAEA], 2005). However, the strong acids used to dissolve the ore body commonly dissolve metals in the host rock as well.

Hierarchical fuzzy-AHP-based multi-criteria decision

In the present study, a hierarchical FAHP-based MCDM model is designed to select the most appropriate mining method for a typical ore deposit. The study considered various intrinsic and extrinsic factors for prioritizing the seven metal mining methods that are considered in the model.

mining - Students | Britannica Kids | Homework Help

Encyclopædia Britannica, Inc. There is a wide range of principal methods that can be used to mine such deposits. Room-and-pillar underground mining methods for many metal and nonmetal deposits differ from those of coal and other softer mineral deposits; these differences are primarily ones of equipment used, method of breaking up the ore, and ways of removing the ore from the mine.

The Calculation and Use of Sulfide Metal Contents in the

 · Calculated sulfide metal contents provide valuable information in mineral exploration and research, but there are few formal descriptions and analyses of the procedures. Sulfide metal contents are best calculated using an assumed value (35.7% S) for a typical pyrrhotite-chalcopyrite-pentlandite mixture, and there appears to be little advantage .
