 · Skinner s presentation advances tools for mines to more efficiently identify nitrate sources in surface and ground water. Mining can result in increased nitrogen levels in groundwater through the use of nitrogen-based explosives. Most commercial explosives contain between 70 and 90 ammonium nitratewhich is highly soluble.

Carpenter (1855–1924) was an American writer of books on travel and world geography whose works helped to popularize cultural anthropology and geography in the United States in the early years of the 20th century.

Can microorganisms be used to control nitrate levels in

 · Biological denitrification for the removal of nitrite and nitrate from mining and mineral processing operations is technically feasible. Nitrification is highly sensitive to both temperature fluctations (particularly temperatures less than approximately 15 ) and the presence of heavy metals. Denitrification is a more robust process.

Effect of Lead Nitrate on Gold Leach Kinetics

 · Lead nitrate is a bit of a tricky one as anyone who has used it can attest and it is essential that you do the theory analysis as well as do lab test work to see if it offers a financial benefit under plant conditions. At one mine site we then tested it at AMMTEC and it worked great. We tested in the lab and nothing happened.
