The Kimberley Process. The Kimberley Process (KP) originated when Southern African diamond-producing states met in Kimberley in 2000 to discuss ways to stop the trade in 'conflict' or 'blood' diamonds and ensure that diamond purchases were not financing violence by rebel movements seeking to undermine legitimate governments.

The Rock Cycle describes how the three main rock types that compose the Earth's lithosphere are constantly transformed into one another through geologic processes. These three rock types are those we learned about in the previous chapter: igneous, sedimentary, and metamorphic rocks.

14.2 The lithosphere (ESBR9). If we were to cut the Earth in half we would see that our planet is made up of a number of layers, namely the core at the centre (separated into the inner and outer core), the mantle, the upper mantle, the crust and the atmosphere (Figure 14.1).The core is made up mostly of iron.
Equipment Used in Gravity Concentration. Selecting suitable gravity concentration equipment is integral for optimizing gold recovery efforts. Below is a list of equipment commonly employed in the mining industry: Mineral jigs: An essential tool for heavy particle separation. Shakers: Utilized to sort materials for different densities.
In modern times several new techniques are used to extract the mineral from the ore, in addition to smelting. The most common methods are flotation, leaching and use of redox reactions. Leaching involves mixing the ore with a carefully chosen liquid that dissolves either the …
Lithosphere, rigid, rocky outer layer of Earth, consisting of the crust and the solid outermost layer of the upper mantle. It extends to a depth of about 60 miles (100 km). The lithosphere is broken up into about a dozen separate, rigid blocks, or plates.
The processes involving weathered rock fragments include erosion and transport by wind, water or ice, followed by deposition as sediments. As the sediments accumulate over …
What are Minerals? The elements or compounds, that occur naturally in the earth's crust, are known as minerals. ... The processes used for removing the gangue from the ore are based on the differences between the physical or chemical properties of the gangue and the ore. ... molten state. In fact, the reaction of iron(III) oxide (Fe2O3) with ...
In the case of artisanal mining, the extraction process usually takes a longer time as it involves low tech equipment and manual labor. Compared to alluvial mining, the post-processing is shorter and is a less resource-consuming task as …

Once the shafts are dug, the miners use drilling machines to extract the potash ore. The ore is then loaded onto conveyor belts and transported to the surface. The miners use specialized equipment to extract the potash ore from the rock. The ore is then transported to the surface for processing. Transportation to the Surface
Uranium recovery involves one of the following extraction processes. In a conventional uranium mine and mill, uranium ore is extracted from the Earth, typically through deep underground shafts or shallow open pits. The ore is transported to a mill, where it is crushed and undergoes a chemical process to remove the uranium.
