Mining Process Ppt Recovery Grade

Artisanal And Small

At this point in the process, direct smelting can often be employed as the final stage of gold recovery. In direct smelting high-grade concentrate is heated until the gold melts. The liquid is then cooled to form a solid mass of gold dore, a semi pure gold alloy, that can reach upwards of 95% purity.

How To Maximize Grade And Recovery Curve

Grade and recovery are inversely related, as increasing the recovery results in decreasing the grade, and vice versa. When we try to upgrade the ore quality in all concentrating processes, we finish by throwing out valuable minerals into the tails (with gangue). On the other hand, when we want to recover more useful minerals, we ... to Maximize Grade and Recovery Curve- Case of Study class ...

Enhanced Methods For Nickel Recovery From Low

Whether high-grade or low-grade, nickel ores need to be processed after mining, in order to upgrade their nickel content from 1-4% Ni to 10-20%. Concentrating the nickel ores usually takes place close to the mine site, and involves chemical and physical processes to crush the ore and separate the nickel-bearing and gangue minerals.

Solution Mining

ISR Process. In-situ recovery involves a series of horizontal parallel wells that injects a solution into an orebody, while a neighboring well extracts the pregnant solution back to the surface. To detect if mining fluids are flowing outside of the mining area, monitoring wells are drilled around the saturation zone.

Cesl Process

The savings in shipping costs allow for the ability to process a lower-grade concentrate. The result can be a significant increase in overall metal recovery, enhancing the economics of the mine. Another advantage of the CESL Process is that bulk concentrates (eg. Cu-Zn, Cu-Ni) can be processed to recover all payable metals.

Open Pit Mining

Large, low-grade ore deposits are usually economically attractive because it permits high recovery of the resource and allows sufficient space for large and efficient mining equipment. An open pit mine could recover almost 90% of the oil shale in a very thick deposit [17]. It is said that strip mining could provide an even higher recovery.
