A low grade copper ore from Palabora was subjected to microwave treatment and then tested for ore strength in a laboratory rod mill using the developing cumulative size distributions of the rod mill products with time to quantitatively determine the effects of microwave treatment on ore strength
Copper extraction refers to the methods used to obtain copper from its ores The conversion of copper consists of a series of physical and electrochemical processes Methods have evolved and vary with country depending on the ore source local environmental regulations and other factors
For example the copper content of a good grade copper ore may be only one quarter of one percent The gold content of a good grade gold ore may be only a few one-hundredths of a percent Therefore the next step in mining is grinding (or milling) the ore and separating the
chalcopyrite milling operation detox The copper milling process involves trucking ore to ore was found associated with copper sulfides chalcopyrite milling operation was in 1943 when Processing method SAG milling ball milling flotation Process throughput Approximately 20 000 mt/yr concentrate Major minerals Bornite chalcopyrite
Photo of Autogenous Mill at a copper mine Autogenous Mills operate mechanically similar to the ball mill They differ in the media they use to break or grind the ore Autogenous Mills use large particles of ore instead of steel or other balls for grinding media Autogenous mills use large pieces of ore
The four major steps in the production of marketable copper are mining concentrating smelting and refining In a few instances however leaching takes the place of concentrating smelting and refining At present although considerable leaching and direct-smelting ores are produced the bulk of the copper ore mined is concentrated The milling of copper ores as practiced in the larger
Therefore pebble crushers are often employed to mechanically break pebbles before they re-enter the AG/SAG mill In a typical copper ore SAG milling operation approximately 20–30% of the recirculating load is presented i e 400–600 t h − 1 pebble rates in a nominal 2000 t h − 1 fresh feed circuit Pebble treatment represents a
