Copper molybdenum flotation

Dec 29, 2021

Separating moly from copper: flowing through the flotation circuit. A $130 million molybdenum (moly) processing plant is being constructed at Newcrest Mining’s Cadia mine in New South Wales. The plant will extract moly from the mine’scopper concentrate stream to produce a 50 per cent moly concentrate in dry powderform, with an anticipated

In fact, in the last century, ores of 4 percent grade were regarded as almost valueless. Today such ores (which would be regarded as relatively rich in copper) are scarce; the great majority of mines contain the
