Upgrading to yield higher er/Fe ratios requires pyrometallurgical and/or hydrometallurgical treatment.The successful beneficiation of lower-grade chromite ores depends on the ore mineralogy, the size requirements of the concentrates, and the chemical composition of the ore. Chromite ore, fluxes, and reducing agents are usually smelted in electric-arc furnaces, adjustments being made to the composition of the charge and the process variables to produce the desired ferrochromium products. Pyrometallurgical techniques are used to produce chromium alloys or additives for the metallurgical industry. Low-intensity magnetic separation can be employed to reject the magnetite, but physical methods cannot be employed to increase the Cr /Fe ratio or to separate the chromites that are present in fine intergrowths with other materials. Gangue materials can be separated by physical methods such as gravity concentration (mainly tabling and jigging).

Differences in the particular quarrying techniques used often stems from variations in the physical properties of the deposit itself.Granite extraction, which is more commonly known as quarrying, consists of removing blocks or pieces of granite stone from an identified and unearthed geologic deposit.

In the embodiment of the invention illustrated in the drawings, I have shown in FIGURE 1 a portable primary rock crushing plant 10, including the main frame struc ture 11 mounted on wheels and axles 12, 12. The Wheel mounted framell may be connected with a tractor 13 through a trailer hitch 14, when it is desired to transport the crushing plant from working place to working place (FIGURE 1).

Depending upon such factors as the number of calciners in the system and the capacities of each, fuel savings considerably greater than in this Example can be achieved, e. at least as high as 40 to 50%.g.It will also be appreciated that the fuel savings evidenced in the present Example are based upon use of a single calciner of a given capacity.

La ® primaria alimenta el material a la cinta transportadora de elevación, la cual lo transporta hacia la criba. Luego que el material es triturado, la revolucionaria cinta transportadora de elevación centrífuga a lo devuelve a la criba en circuito cerrado. El material de gran tamaño es llevado al chancador de cono y el material harneado se divide a las cintas transportadoras de productos.
