Hardrock mining exposes rock that has lain unexposed for geological eras. When crushed, these rocks expose radioactive elements, asbestos-like minerals, and metallic dust. During separation, residual rock slurries, which are mixtures of pulverized rock and liquid, are produced as tailings, toxic and radioactive elements from these liquids can ...

What is the health and safety problem? Detonating explosives release toxic gases, primarily oxides of nitrogen and carbon monoxide. Nitric oxide (NO) and nitrogen dioxide (NO 2) are produced by large surface blasts in which the explosive does not detonate properly.NO released by the detonation oxidizes to NO 2 as the fumes mix with the atmosphere. . Excessive NO 2 production is …
Quaternary unconsolidated porous aquifers are crucial to industrial, agricultural, and domestic water as well as ecological requirements in semiarid regions. Underground mining can influence aquifers even when they are located out of the fractured zone. Slight but continuous leakage should not be ignored.

INTRODUCTION. Environmental protection has become the focus of world-wide researches in the gold mining industry and favors the development of environmentally sound processes, such as the Coal-Gold Agglomeration (CGA) process, which is an alternative to existing gold processing methods, such as cyanidation and mercury amalgamation.
A burgeoning mining industry stimulated early growth in the Arizona Territory, and by 1864 nearly 25 percent of the male, non-native populace was prospectors. By the 1870's a plethora of hardrock mines were yielding prodigious volumes of copper, lead, zinc, silver and gold ore. In 1912, the newly christened state of Arizona supported 445 ...
