Role of NRF2 in the Pulmonary Response to Inhaled Mine ...

The mechanisms underlying arsenic dust toxicity in lung tissue have not been fully elucidated. We have recently demonstrated that arsenic exposure activates the Nrf2 pathway and that while acute activation of Nrf2 can be protective, prolonged activation of Nrf2, which may occur in populations chronically exposed to arsenic, may be harmful.

Uses of Copper | Supply, Demand, Production, Resources

In porphyry copper deposits, copper ore minerals are disseminated in igneous intrusions. Sediment-hosted stratabound copper deposits, in which copper is concentrated in layers in sedimentary rocks, account for about 20 percent of the world's identified copper resources. Globally, mines in these two deposit types produce about 12 million tons of ...

Jul 20, 1998 · This conclusion is in agreement with the recent finding that the solubilization of Cu 2+ from a copper ore is determined by the sulfur-oxidizing activity of T. ferrooxidans . The addition of iron ions to cultures of T. ferrooxidans growing with hydrolyzable, synthetic, iron-free sulfides generally enhanced leaching rates (25, 26).

Innovations: Introduction to Copper: Mining & Extraction

The techniques for extraction of copper from oxidized ores are quite different from those employed for the sulfide ores. The oxidized ores, consisting of the silicates, carbonates and sulfates, are treated by several methods, all involving some form of leaching of the crushed ore with sulfuric acid to produce impure solutions of copper sulfate.

From Ore to Finished Product - copper

Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.

Bioleaching: A microbial process of metal recovery; A review. This sulfide dissolution can be affected by 'direct' and 'indirect' mechanisms. In the 'indirect' mechanism bacteria oxidize only dissolved iron (II) ions to iron (III) ions and the latter can then attack metal sulfides and then be reduced to iron (II) ions.
