Iron is extracted from its oxide ore (hematite) and requires a number of treatments to render it acceptable as a blast furnace feed (i) Crushing and sizing: The ore is crushed in jaw or gyratory crushers except for sticky and clayey ore, for which double roll crushers are commonly adopted. The ore is broken to small pieces of 25-55 mm (1-2.5 inch).

Typical sulphide ore flotation dosage of collectors used industrialIy are about 0.02 to 0.2 pounds per short ton of ore, or 10 to 100 gm per metric tonne of ore. These ranges translate to approximately 5 mgjl to 50 mgjl or 0.029 to 0.29 mol/litre of the water phase, for the molecular weights of the typical xanthates studied.

After the feldspar ore is drilled and blasted, secondary breakage occurs by means of drop balls. Ore is then loaded by hydraulic shovel onto trucks for transport or directly in the adjacent crushing plant. The crushing is done by. means of a jaw crusher, gyratory crusher and then by rod mills. The slime is frequently removed with hydrocyclones.

Bronze and gunmetal scrap yield mixtures of oxides from which tin lead solder is made. The treatment of nickel alloys (e.g., German silver, a Cu-Ni-Zn alloy) is difficult because of the tendency of nickel to form slag. Methods have been developed that let the nickel pass into the electrolyte during copper electrolysis (see Chapter 12). Summary.
