Mining activities are not new and indeed may have started in Neolithic (Chalcolithic) times to obtain the first metals for tool fabrication (Reardon 2011).In the Classic Greece and in the Roman Empire, many mines were exploited for production of iron, lead, copper, gold, and other metals.
1.1 PHASES OF A MINING PROJECT There are different phases of a mining project, beginning with mineral ore exploration and ending with the post-closure period. What follows are the typical phases of a proposed mining project. Each phase of mining is associated with different sets of environmental impacts. 1.1.1 Exploration
Production of Lead, Zinc and Tungsten in India! Lead is a widely used metal due to its malleability, softness, heaviness and bad conductivity of heat. The most important industrial use of lead is as a constituent in alloys such as type metal, bronzes and anti-friction metal.
Zinc (Zn) still represents an important health problem in developing countries, caused mainly by inadequate dietary intake. A large consumption of cereal‐based foods with small concentrations and low bioavailability of Zn is the major reason behind this problem.
