complex ore

It continues to be a world leader in developing processes for treating complex ores.

The most widespread resources are zinc- and lead-containing complex ores.

The mountains are rich in complex ores.

These recoveries are some of the highest seen to date with Duluth Complex ores.

The first discovery was made at the Alpha mine in 1869, but the silver could not be extracted at a profit from the complex ores.

O'Brien doing research on the complex ores from Cobalt, Ont., area.

In metal and mineral processing, our teams are finding ways to process complex ores that others are unable to process cost effectively.

The ores are complex ores, they contain copper, gold, silver, bismuth, and other metals besides tungsten.

Eddie McLean (Ausenco) - Complex ores or complex design?

Fine grained complex ores require fine grinding and several flotation steps to produce concentrates of sufficient grade to be sold to smelters.

Locally variable metamorphism and deformation has produced texturally and mineralogically complex ores – typically difficult and energy intensive to process.

With two physicians, William Forrest and Robert Wardrop Forrest, he formed a private research syndicate, seeking improved methods of recovering gold from complex ores.

More Complex Ores As the relatively simple-to-process mineral deposits are consumed, ways have to be found to process the more complex ores.

A subsidiary of Complex Ores - the Hydro-Electric Power and Metallurgical Co. Ltd - was formed in 1911 to help finance the hydro-electric development needed to power the plant.

The world's gold-mining industry was stagnating, refining only about 45 per cent of metal from complex ores: the new process enabled 98 per cent extraction, and was hailed as the saviour of the industry.

Strategic research alliances between CANMET-MMSL and the private sector have brought improvements in mining technology, such as better ways of processing complex ores and better techniques for making low-grade deposits economically viable.

In 1908 he floated his company, the Complex Ores Co. and planned to open a plant in Tasmania, using hydro-electric power from the waters of the Great Lake and the Ouse and Shannon rivers.

Aberfoyle was investigating the possibility of using the Sirosmelt lance approach to improve the recovery of tin from complex ores, such as its mine at Cleveland, Tasmania, and the Queen Hill ore zone near Zeehan in Tasmania.

The Swansea smelters became so adept at recovering gold and silver from complex ores that in the 1800s they received ore concentrates from the United States, for example from Arizona in the 1850s, and Colorado in the 1860s.

Kootenay Mining Region, Rossland Gold Mines, B.C. British Columbia's Kootenay Region has long been recognized as one of Canada's leading hard rock mining regions, and as a world leader in refining complex ores.

The solvent is useful for concentrating and purifying the valuable metal solutions of low-grade complex ores and is already being used by India's nuclear industry at various commercial operations for the separation and recovery of Zinc, Cobalt, Nickel and Rare Earths.
