Crude zinc ashes (also called zinc skimmings) are the residues left behind in the galvanising bath after the hot dip galvanising of steel. The zinc ashes appear as a thin layer on the surface of the galvanising bath, and are removed after each cycle. Among other things, Rezinal processes zinc ashes received from hot-dip galvanising (construction), zinc-coating of wires and pipes, and zinc smelting residues. An ecological solution, since it keeps the chain closed, and zinc ashes are converted into valuable raw materials.
Brass ash of composition (wt-%) 59·67Zn-9·22Cu-1·45Pb-2·61SiO2-0·36Cl was treated by carbothermal reduction in a temperature controlled tube furnace. The aim of the work was to collect zinc in the form of metal and/or zinc oxide in the gaseous phase. Treatment temperature (950-1200°C) and time (15-180 min) were varied. At 1200°C and 60 min, recovery of zinc was 92·5% and zinc content in the remaining residue was found to be 12·8 wt-%. Kinetic analysis of the experimental results showed that initially the reaction was under chemical control with an activation energy of 90·1 kJ mol-1. Subsequently the development of a sintering structure caused the reaction mechanism to change to diffusion control.

Principal forms in which copper ores are found include native copper, porphyry copper, massive deposits, and mixed ores. Native copper is simply the metal found unadulterated in nature. Occasionally copper is still found in its native form, but more frequently it is mixed with other minerals, some of which may have value themselves. The amount of copper in an ore can vary from 0.4 percent to more than 12 percent. Porphyry copper deposits, in which the copper materials are more or less uniformly scattered throughout the rock, account for the greatest tonnage of metal in the producing areas of the world. The copper minerals in the upper portions of such deposits are in general oxides (copper chemically combined with oxygen), those in the lower levels sulfides (copper with sulfur). The host rock is porphyry, schist, or other rock. Massive deposits are of higher metal content but of more limited extent; they may be oxidized in the upper portion with sulfides lower down. In mixed ores, nickel, zinc, or lead can accompany the copper; when such ore is mined, these other metals also are refined and sold as by-products.
There are only a few deposits of oxide lead ores, some of which are processing plants. These include Mibladen Mine in Morocco, several deposits in Sardinia and Tynagh deposit in Ireland. In general, the mineral composition varies significantly. The limestone deposits contain barite and dolomite. In these ores, lead is represented by cerussite with little to no galena present. The oxide lead ore in a dolomitic matrix may contain clay slimes and a fairly large amount of pyrite and barite; both of these minerals have a negative effect on oxide lead flotation. These ores may contain one or several lead minerals, including cerussite, anglesite and pyromorphite. Some lead oxide ore varieties may contain oxide copper minerals in the range of 0.2–1% Cu.
