Axial Depth of Cut = AD. For Tool Diameters 1/8 and Under: AD = Dia. of Tool X 0.25 to 0.05. For Diameters above 1/8 AD = Dia. X .05 to 1.5. SFM and Feed. For AD between 0.25 to 0.5 of Tool Dia. SFM = 0.8 Lowest Range Value. Feed at Suggested Value. For AD equal and above Tool Dia. SFM = 0.8 X Highest Speed Range.
A fungus, A. niger could leach 47% Cu, 50% Ni, and 23% Co from the slag. Biogenerated organic acids could complex metals present in slag particles [75–77]. Bioleaching of tailings and slag from a flotation and smelting plant to recover copper and nickel was also tried using A. ferrooxidans [78]. From flotation tailings about 16% Cu and 45% Ni ...
