Feed for the cell is pulled after the second rougher cell
ina row of Wemco 3,000-[ft.
A multistage flotation circuit, comprising 24 rougher cells
, 12 scavenger cells and 10 column cells produces copper concentrate with gold and silver byproduct metals.
3] capacity rougher cells
and two rows of six 128 [m.
The final stage in the production process includes a series of rougher cells
, where the pulp is chemically treated to separate the copper, molybdenum and silver from the gangue.
Sulphide flotation begins in five banks of mechanical rougher cells
for a total retention time of 25 mm.
This is conducted in closed circuit with the cyclone overflow reporting back to the rougher cells
The cyclone undersize from mill 1, 2, and 3 each feed two banks of 15 rougher cells
With the pyrite rougher cells
available, a plumbing rearrangement was in order.
For cleaning, the product from the first three rougher cells
passes to a 0.
Each Cu-Mo flotation circuit will consist of four lines of eight rougher cells
Smoother, more continuous flotation-cell operation because of reduction of excess froth in the rougher cells
