Copper Mining, Processing, Production & Mine Services

Gibraltar Development Plan 3 (Gibraltar Mines Ltd) in Canada Ausenco provided EPCM services for the third phase of the development of the Gibraltar copper-molybdenum mine. The project increased the overall processing capacity to 85,000 t/d (an increase of over 30,000 t/d) with annual copper production averaging 165 million pounds.


US3672579AProcess for beneficiating magnetite iron ore

A process for upgrading low-grade magnetite-containing iron ore with minimum fine grinding. The dry ore is first comminuted to between about three-fourths inch and 10 mesh particle size and magnetically separated. The dry tailing is discarded and the concentrate is ground to between about 20 and 100 mesh and again subjected to dry magnetic separation.
