Like the spirals, washwater aids in the separation of the particles while increases the entrainment of the gangue in the concentrate.
22.
Violarite mineralisation requires different metallurgy to primary nickel sulfides, due to the different nature of its gangue and its flotation properties.
23.
The entire convenient mineral was collected and the abandon shafts carefully refilled with gangue and rocks ( Mohen 1992; 85 ).
24.
The ore often consists up to 100 % lead-zinc sulfides, with little or no pyrite, chalcopyrite or gangue sulfides.
25.
As it travelled upwards, it met with small jets of water which gradually washed the gangue off the bottom of the belt.
26.
For example, at Mount Gabriel, it was estimated that they extracted the astonishing number of of rock, gangue and ore.
27.
The mullock is mined and piled in waste dumps, and the gangue is separated during the beneficiation process and is removed as tailings.
28.
These particles are then separated to remove gangue, thereafter followed by a process of physical liberation of the ore minerals from the rock.
29.
It took crews eight months to remove of gangue and penetrate eleven reinforced concrete partition walls ( each thick ) to reach the graves.
30.
Once the ore had been brought out of the mine it had to be separated from rock and other vein minerals ( gangue ).
