copper element information, properties and usesa reddishg metal that is easily worked and drawn into wires. copper is obtained from these ores and minerals by smelting, leaching and electrolysis. reserve distribution, production concentration, substitutability, recycling rate and political stability scores. crustal abundance (ppm) the number of atoms of the element per 1 millionphotos of g ores, quartz, telluride g ore and gg and silver are obtained from a variety of ores. most people think of nuggets and such, but the truth is that very little comes from nuggets nearly all newly mined g comes from ores mined from the natural hard rocks that contain g in tiny, even microscopic particles.zinc (zn) chemical properties, health and environmentalzinc is the 23rd most abundant element in the earth's crust. the dominant ore is zinc blende, also known as sphalerite. other important zinc ores are wurzite, smithsonite and hemimorphite. the main zinc mining areas are canada, russia, australia, usa and peru'.copper mining and processing processing copper orpper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.the most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different

Advantages of concentration of g ores

ore ore is natural rock or sediment that contains one or more valuable minerals, typically containing metals, that can be mined, treated and s at a profit. ore is extracted from the earth through mining and treated or refined, often via smelting, to extract the valuable metals or minerals. the grade of ore refers to the concentration of the desired material it contains.g processing mining and concentrating britannicag processing g processing mining and concentrating the nature of the ore deposit determines the mining and mineral processing techniques applied. oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. in this case they are merely shattered by explosives and then piled into heaps forg processing britannicaendogenetic g ores include vein and lode deposits of elemental g in quartzite or mixtures of quartzite and various iron sulfide minerals, particularly pyrite (fes 2) and pyrrhotite (fe 1x s). when present in sulfide ore bodies, the g, although still elemental in form, is so finely disseminated that concentration by methods such asores and minerals definition, types differences with4. what type of mineral is g? ans g has almost always traced of silver in its natural mineral form, and it can also contain traces of copper and iron. 5. what are the main ores of zinc? ans sphalerite (zinc blende), a mineral of zinc sulphide, is the most common zinc ore. you now know about ores and minerals.g extraction g extraction refers to the processes required to extract g from its ores.this may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.. g mining from alluvium ores was once achieved by techniques associated with placer mining such as simple g panning and sluicing, resulting in direct recovery of
