This ore processor works for silver, copper, tin, gold, and iron ore. The process can begin as early as the slag furnace which can be powered by a Furnace Heater or by basic fuels. An ore has a 40 chance of producing stone and 120 chance for the ingot. Note that silver however has a 100 chance of producing silver and a 120 chance of ...
In this process copper ore is mined, crushed, ground, concentrated, smelted and refined. The mining, crushing and grinding portions of the processing are extremely energy intensive since the rock must be reduced essentially to talcum powder fineness in order to separate the copper-bearing minerals from it.
This copper flotation process is suitable for treating the ore with coarse uniform disseminated grain size. The combination between copper minerals and gangue is loose, and the contact edge is smooth and flat. When the raw ore is grinded to -200 mesh accounting for 50-60, the copper minerals can be basically monomer dissociated.
Oxide removal from copper, brass, bronze, nickel silver and other copper alloys containing high percentages of copper. 10 to 25 hot sulphuric acid with 5-10 potassium dichromate added. Pickling can be done at same time flux is removed.
polyacrylamide is widely used as a flocculant or filter aid in mining minerals such as gold, silver, copper, aluminun, iron, tin, coal, lead, zinc. For this industry, the molecular weights of the anionic polymers will range from low to very high. These polymers are used to separate mineral particles of different sizes and densities and separate them from the water they are suspended in.
Mechanical milling followed by sieving was able to separate silver from copper while chemical separation using sulphuric acid was able to detach the semiconductor material.
