Largescale mining operations, especially those using openpit mining techniques, can result in significant deforestation through forest clearing and the construction of roads which open remote forest areas to transient settlers, land speculators, and smallscale miners.
Galena, or lead sulfide, the world''s major source of lead ore, occurs worldwide and, it is mined in many countries, including the United States, Australia and China. Lead ore comes from underground mining operations, where the lead ore seams are blasted out of the ground and transported to
Lead Production & Statistics. Lead ores are mined at a rate close to 5 million tonnes a year and the world market for refined lead stands at about US $15 billion. While it has a high economic value, lead is relatively economical to produce. As with all metals, there are two main production routes.

This process is called surface mining and was widely used as a method for extracting coal in the Ohio River valley and in England. This technique is also used for mining phosphate deposits, gypsum, gravel, limestone, copper, iron, and other minerals.
Nyrstar also recovers gold in the lead refining process. Silver. Silver is produced in concentrate from our mining operations. Nyrstar also recovers silver from the lead refining process as a silver doré and as a byproduct from the zinc refining process into various leach products. Indium
Primary production from mined lead ore is of course the original source of all lead, but secondary production, where it is recovered from recycled products or from residues arising from the production process is of enormous importance. Secondary lead production now accounts for more than half of all lead produced throughout the world.
From its original home buried underground in a mine to its use in a finished product such as wire or pipe, copper passes through a number of stages. When it is recycled it can pass through

We also sell gold and silver, which are typically mined together with zinc and lead ores. We market zinc and lead not only from our own facilities, but also from thirdparty
Mining is an inherently invasive process that can cause damage to a landscape in an area much larger than the mining site itself. The effects of this damage can continue years after a mine has shut down, including the addition to greenhouse gasses, death of flora and fauna, and erosion of land and habitat. An example of the scarred land of a
Lead is a very corrosionresistant, dense, ductile, and malleable bluegray metal that has been used for at least 5,000 years. Early uses of lead included building materials, pigments for glazing ceramics, and pipes for transporting water.
