nickel mining procedure

Copper-nickel mining (also known as "non-ferrous mining") in northern Minnesota is not a new issue for the state. Copper-nickel deposits have been known to exist in northern Minnesota since the 1800s, but it was not until 1948, when deposits were discovered near Duluth, that serious interest in mining these metals developed in the region.

Improved technologies in mining, smelting and refining, as well as increased capacities, also allow for lower-grade nickel ore to be processed. Decreasing ore grades are therefore not necessarily a sign of diminishing resources, but a reflection of innovation and improvements made …

Sep 11, 2020· On top of that, with nickel being one of the most technically challenging metals to process and refine, and every operation being unique, further challenges will also be asset dependent (Exhibit 1). For miners, the type of ore deposit—sulfide or oxide (or laterite, further subdivided into saprolites and limonites)—defines the whole value chain.

437 Nickel Smelting and Refining Wet scrubbimg should be avoided and cooling waters should be recirculated. Storm waters should be collected and used in the process. Process water used to transport granulated slag should be recycled. To the extent possible, all process effluents should be returned to the process. Treatment Technologies

Workers in metal mining and processing are exposed, not only to the metal of interest, but also to various other substances prevalent in the industry, such as diesel emissions, oil mists, blasting agents, silica, radon, and arsenic. This chapter examines cancer risk related to …
