How Do you separate copper ore from rocks answersUsing salt to refine silver Colorado Central Magazine

Silver is found as veins of ore within other rocks often near veins of lead zinc or copper After this various acids are used to separate the other unwanted material from the copperTo recap this process consisted of crushing the silver ore in a Spanish arrastra or an American stamp mill and roasting it with rock salt That converted a silver sulfide hard to separate into a silver chloride easy to separate Sometimes when the ore was especially rich droplets of

How Is Iron Extracted From the Earth ReferenceGold extraction Wikipedia

Iron ores in the form of hematite ferrous oxide and magnetite are removed from the earth through mining The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore however because iron does not occur naturally it is necessary to use a blast furnace to separate or refine iron from the other substances in the iron oreGold extraction refers to the processes required to extract gold from its orThis may require a combination of comminution mineral processing hydrometallurgical and pyrometallurgical processes to be performed on the ore Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing resulting in direct recovery of

Magnetic Separation Method Mineral Processing MetallurgyHow do you separate gold from other substances Finishing

Magnetic separation is a process used to separate materials from those that are less or non 173 magnetic All materials have a response when placed in a magnetic field although with most the effect is too slight to be detected The few materials that are strongly affected magnetised by magnetic fields are known as “Ferromagnetics” those lesser though noticeably affected are known as 1 One way is by panning since gold is heavier than most other substances you can swirl water just fast enough that the gold stays in the pan while the other substances wash out Or 2 You can put everything into an acid that dissolves other substances and doesn t dissolve gold Or 3
