Extracting from the Cheap Messika Bracelet Ore
Silver ore from replica messika jewelry the mines is crushed with batteries of stamps, then mixed with water and shaken on tables or in agitators which cause the heavier metal to fall to the bottom. The pulp is passed over a magnetic pulley, which draws out the steel and iron, and is “dewatered” by means of screens. The process of crushing, mixing with water, and concentrating is repeated until the ore is very fine, being finally ground in a tube mill. It is then cyanided to extract it from metallic compounds and precipitated as a silver sulphide. For the process of desulphurizing it is put in revolving cylinders filled with ingots of aluminum. The motion of the cylinders produces hydrogen, which extracts the sulphur.
Another method of separating the metallic ore from the rock is called "floatation." When the ore has been crushed and mixed with water a quantity of oil is added and the slimy pulp is floated over water in "flotation cones." The oil attaches itself to the mineral, enclosing tiny air bubbles which cause it to rise to the surface of the water where it is skimmed off. The replica dior eclat sunglasses mass flows through a series of compartments where this process is repeated. By alternately shaking it so that it is thoroughly aerated and allowing it to settle while the froth rises to the surface, all the metal is recovered. This method requires less space and less elaborate machinery than the ordinary process.
