eccentric shafts with meshed gears. The shafts are rotated by the motor, due to which the feeder is vibrated. Due to the vibrations, the materials will fall, and move forward. The small parts are passed through the screen, preventing additional crushing.
Furthermore, the method of surface mining used by mostly registered large-scale, small-scale and unregistered artisans often results in the excessive destruction of productive land, deforestation and mass trenching.  add that productive arable lands have been left bare without any form of protection thereby increasing the runoff and causing turbidity (Plate 7). According to , the exploitation of mineral resources often leads to extensive soil degradation through the destruction of vegetation and alteration of microbial communities, resulting in low soil fertility and productivity. The Food and Agriculture Organization estimated that between 1990 and 2005, gold mining activities in Ghana contributed significantly to land degradation and loss of cultivable land, resulting in a massive loss of forest cover (26%) and arable lands (15-20%) at the Tarkwa, Ayanfuri, Dunkwa, Esaase and Bogoso mining areas in Ghana .
The mechanism of the principal stage of briquetting—compressing of the raw material into the desired shape—may be described as follows. At low pressures there is an external compacting of the material caused by reduction of the spaces between particles. The particles themselves are then compressed and deformed, and a molecular bond is created between the particles. High pressures at the end of the process cause a transition from elastic deformation of the particles to plastic deformation, which strengthens the briquette and enables it to retain a given shape. The physical and chemical properties of the raw material are a major factor affecting the nature of the deformations.
There is need to establish environmental oversight groups with a singular mandate of protecting the environment in mining communities as a local initiative and a bottom-up approach in getting community members engaged in environmental governance.
