For example, chalcopyrite and bornite are easily depressed by lime and cyanide. This is mainly because the outer electrons of the copper atom are 3d 10, which is full, so copper atom has low reactivity. For iron atom, the outer electrons are 3d 6, which has an unoccupied orbital, so iron atom shows more reactivity. (2)

· Pulp Densities. Pulp densities indie by means of a tabulation the percentages of solids (or liquidtosolid ratio) in a sample of pulp. This figure is valuable in two ways—directly, because for each unit process and operation in milling the optimum pulp density must be established and maintained, and indirectly, because certain important tonnage calculations are based on pulp density.
· Although basic porphyry copper flotation and metallurgy has remained virtually the same for many years, the processing equipment as well as design of the mills has continually been improved to increase production while reducing operating and maintenance costs. Also, considerable attention is paid to automatic sensing devices and automatic controls in order to assure maximum metallurgy and ...
Two HQ diamond drill holes were drilled in the Bornite deposit, specifically to obtain representative material for use in metallurgical testing. Five main metallurgical composites were prepared from whole core obtained from this drilling and the composite samples are .

Chalcopyrite has a golden yellow color, which often resembles, its physical properties such as streak and tenacity are very different from Gold and can easily distinguish it. Chalcopyrite is a beautiful mineral, with good crystals being fairly common.
· molecular formula is C2H10N2. moles of compound in g = / = moles. there are 10 moles of H in a mole of the compound so we have moles of H in the mass. so number of atoms = *10 ^23 atoms / mol * mole. = *10^23 atoms of H in the sample mass.
