Design of a crushing system that improves the crushing
The ore usually has to pass various crushing stages, each reducing the ore to a certain size Crushing plant layout is of vital importance Goldcontaining rocks are crushed for several reasons Crushing reduces the physical size of large rocks, exposing more surface area of rock, thus exposing any gold that may be in the rock and increasing The method is applicable to a wide range ores with varying mineralogies Significant variation in the amount of barren rejectable gangue for a given gold ore and a given gold loss to rejects was observed for the various crushing technologies at the same 100% pass size, even though the particle size distributions were fairly similarAssessing the amenability of a free milling gold ore to An obvious drawback of this method is the toxicity of mercury2,3 The health risk of mercury is well known today in many parts of the world, but in remote smallscale mining (SSM) communities that knowledge is still scarce4 Gold extraction by amalgamation releases large amounts of mercury into the environment as metal mercury, which is later transformed to metholated mercury, a powerful The Borax Method of Gold Extraction for SmallScale Miners
