Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).Porphyry Deposits: The World’s Largest Source of Copper,,The ability to achieve close control of porosity and pore size is the basis for the use of metal powders as filters. Most producers prefer spherical powder of closely controlled particle size to permit the production of filters within the desired pore size range. Tin bronze is probably the most widely used filter material but nickel silver and copper-nickel-tin alloys are also used. The effective pore size can be varied widelyCopper Standards - ASTM,Standard Specification for Threadless Copper Pipe, Standard Sizes: B306 - 20: Standard Specification for Copper Drainage Tube (DWV) B315 - 19: Standard Specification for Seamless Copper Alloy Pipe and Tube: B359 / B359M - 18: Standard Specification for Copper and Copper-Alloy Seamless Condenser and Heat Exchanger Tubes With Integral Fins: B360 - 20Acid Leaching - Copper Ore Treatment Method,23.05.2017· In leaching plants of capacity illustrated by this flowsheet recovery of copper normally effected range from 80 to 90% of oxide copper and 70% or more of sulfide copper from average ores.
