Mining risks: Coal, uranium, phosphate, bauxite, iron ore

Coal mining risks. Coal mining has been one of the most common (and dangerous) forms of mining for a number of years. Thousands of people have died in coal mines, and hundreds continue to face the safety hazards of mining coal. In addition, the infrastructure around mines such as colliery spoil tipes have collapsed in the past, damaging the environment and killing people.

Roles of bioavailable iron and calcium in coal dust

In the present study, we examined the ability of 28 coal samples to release bioavailable iron (BAI) and calcium, as well as other metals such as Cr, Ni, Cu, and Co, from three coal mine regions in Utah (UT), West Virginia (WV), and Pennsylvania (PA), respectively. BAI is defined as iron (both Fe2+ and Fe3+) released by the coals in 10 mM phosphate solution, pH 4.5, which mimics conditions of

Feasibility and cost of creating an iron-phosphate coating

Acid mine drainage (AMD) occurs when sulfide minerals are exposed to an oxidizing environment. Most of the methods for preventing AMD are either short-term or high cost solutions. Coating with iron phosphate is a new technology for the abatement of AMD. It involves treating the sulfide with a coating solution composed of H2O2, KH2PO4, and sodium acetate as a buffer agent.
