Apr 29 2018 Environmental Impacts of Nickel Mining and Processing. Posted by Adrienne Krieger on April 29 2018. Nickel is a widely used alloy in the jewelry industry as an additive to make a variation of white gold. We sometimes refer to this type of white gold as nickel-white however it is the standard in the US and when talking about white gold.
Cadmium has many chemical similarities to zinc and is often recovered from the primary zinc ore sphalerite. The single most important use of cadmium is in the production of nickel-cadmium Ni-Cad batteries. Relation to Mining. Cadmium rarely appears in nature and is most commonly sourced by its removal from zinc metals during the refining process.

Cadmium is a heavy metal of considerable environmental and occupational concern. It is widely distributed in the earths crust at an average concentration of about 0.1 mgkg. The highest level of cadmium compounds in the environment is accumulated in sedimentary rocks and marine phosphates contain about 15 mg cadmiumkg .
Occupational and environmental exposure to heavy metals silica and asbestos can occur during mining and milling operations. The smelting process extracting the metal from the ore is associated with the highest exposures and environmental releases. The hazards to human health caused by exposure to heavy metals – including lead cadmium and .
Feb 01 2010 Lead and cadmium concentrations in tailing and waste rock samples are listed in Table 2. The results found that Pb level in mining wasters was within range of earth crust 17 while Cd content varied largely from 0.70 to 79.92 gg significantly higher than 0.1 0.2 gg of the earth crust18.
