Ore is loaded into underground equipment and transferred to orepasses, wher e the ore is dumped. A drawpoint or chute is usually situated at the outlet of the pass on the lower level, where the ore is loaded and transported to the underground ore bins or direc tly to the main haulage level.

For the extraction of highly reactive metals from their ores electrolysis is used and for extraction of metals of medium reactivity calcination, roasting and reduction methods are used. While metals of low reactivity are extracted from their ores by roasting and refining.

the gold from ore, carbon adsorption to extract the gold from the cyanide solution and electrolytic refining and chlorination to refine the gold. The LCA assessed production from both nonrefractory ores, which are relatively easy to treat, and refractory ores where the gold is 'lockedin' and requires more complex processing.

Smelting Furnace of Iron Ore Laboratoryscale experiments showed that pig irons and steels of acceptable grade can be made by arcfurnace methods from east Texas siliceous ores containing less than 25 percent iron. Under highly reducing conditions, 97 to 99 percent of the iron in the ore was recovered as pig iron. Small quantities of limestone, the minimum limited only by progressively higher ...

 · Extraction and refining. The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of highertemperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel production.
