1. Introduction. The development of modern society is based on the need to fill a demand for goods and services therefore industry must evolve and adapt to be able to provide and bring to market those products Kogel et al. 2006.The first step in that process is the supplying of raw materials for further processing and transformation.
The selection of the mine design is dictated by the physical structure and value of the ore body and by the characteristics of the adjacent geological materials. Although open-pit mines and underground mines are the two most common mining strategies placer mining and solution mining also have been used for mineral extraction.
2019-6-27 · A magnetometer is a device that measures magnetism—the direction strength or relative change of a magnetic field at a particular location. The measurement of the magnetization of a magnetic material like a ferromagnet is an example.A compass is one such device one that measures the direction of an ambient magnetic field in this case the Earths magnetic field.
Nickel Smelting and Refining Industry Description and Practices Primary nickel is produced from two very dif-ferent ores lateritic and sulfidic. Lateritic ores are normally found in tropical climates where weath-ering with time extracts and deposits the ore in layers at varying depths below the surface.

• Significant potential environmental risks are associated with extreme natural events and failures in management practices. Extreme natural events e.g. hurricanes earthquakes intense rainfall events drought have the potential to lead to the release of contaminants if facilities are not designed and constructed to withstand such events or fail to perform as designed.
