1.1 PHASES OF A MINING PROJECT ... The gold content of a good grade gold ore may be only a few one-hundredths of a percent. Therefore, the next step in mining is grinding (or milling) the ore and separating the relatively small quantities of metal from the non-metallic material of the ore in a process .

Gold processing, preparation of the ore for use in various products. For thousands of years the word gold has connoted something of beauty or value. These images are derived from two properties of gold, its colour and its chemical stability. The colour of gold is due to the electronic structure of

The new gold recovery plant thus incorporates state-of-the-art technology, with a degree of automation that helps to minimize manpower and to reduce operating costs. The gold is milled in a two-stage process, first through a grind mill followed by a ball mill in closed circuit with a cyclone cluster.

New Caledonia has the longest history of mining in the Pacific islands. Nickel was found in New Caledonia in 1864 by the engineer Jules Garnier. It was distributed in the ore layers which cover about one third of the area of the main island of New Caledonia. The nickel concentration was inhomogeneous and also varied with the depth.

The nickel content of laterites varies widely: at Le Nickel in New Caledonia, for example, the ore delivered to the smelter in 1900 contained 9 percent nickel; currently it contains 1 to 3 percent. Mining. With nickel found in two radically different types of ore, it is not surprising that the mining methods differ.

Yet mining the ore is just one stage in a long and complex gold mining process. Long before any gold can be extracted, significant exploration and development needs to take place, both to determine, as accurately as possible, the size of the deposit as well as how to extract and process the ore efficiently, safely and responsibly.
