    1. Most of the antimony mined each year comes from China, which supplies over three-quarters of the world’s total. The remainder is from Russia, South Africa, Tajikistan, Bolivia, and a few other countries, including the United States. Some antimony is produced as a by-product of smelting ores of other metals, mainly gold, copper and silver, in countries such as the United States, Canada, and Australia.

      Top antimony producing countries

    1. A 2009 study published in PLOS One concluded that the global warming potential of mining and processing nickel was the eighth highest of 63 metals over the previous year.

      The mining and processing of nickel has one of the biggest effects on global warming out of 63 metals.

    1. The pond, owned by the Inner Mongolia Baotou Steel Rare-Earth Hi-Tech Company, or Baotou Steel, lacks a proper lining and for the past 20 years its toxic contents have been seeping into groundwater, according to villagers and state media reports.

      Lanthanum Toxins have been leaking into the ground water which people use for tap water.

    1. Damage to water sources that residents attribute to mining, as well as increased demand due to population migration to mining sites, reduces communities’ access to water for drinking, washing and cooking. Women, who are primarily responsible for fetching water, are forced to walk longer distances or wait for long periods to obtain water from alternative sources. The dust produced by bauxite mining and transport smothers fields and enters homes, leaving families and health workers worried that reduced air quality threatens their health and environment.

      Mining is contaminating our water sources and water is one of the most important things for survival.

    1. Drift mining utilizes horizontal access tunnels, slope mining uses diagonally sloping access shafts, and shaft mining utilizes vertical access shafts. Mining in hard and soft rock formations require different techniques.

      So different kinds of mining use different tunnel systems, how do we decide which kind is best in each situation?

    1. Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices.
