The work-index is a parameter used in ore milling processes. It is defined as the energy needed to reduce ore from infinite size to the state where 80% of the milled ore will pass through a 100 mesh screen. ... W = Power consumption of the mill (kWh/t) W i = work index (kWh/t) F = 80% passing size of the feed to the mill (microns) P = Required ...

Natural oxidation to form the secondary zone had resulted in a concentration of silver and lead, and ore from this section of the ore-body could be smelted directly. The underlying sulfide zone, which comprised the bulk of the …

Silver contained in the mill ore was estimated at 869.52Moz, whereas the heap leach ore reserves were estimated to contain 42.28Moz of silver. The poly-metallic mine containing gold, silver, lead and zinc is owned and operated by Goldcorp.

the ore grade and the mass of ore to be mined and processed per kg recovered uranium. At a grade of 0.1% uranium, one megagram (1 Mg = 1 metric tonne) of rock has to be mined and processed to obtain 1 kg uranium in the mill. This is ten times as much as from rock at a grade of 1%, containing 10 kg uranium per Mg rock.

The specific energy in comminution can be calculated by applying Bond's equation (Skarin and Tikhonov, 2015; Wills and Napier-Munn, 2006) (equation (1)): (1) W = 10 W i (1 P 80 − 1 F 80) E F x where W is the specific energy consumption of the mill (kWh/t), Wi is the work index measured in a laboratory mill (kWh/t), P80 and F80 are 80% of the ...

Fine grinding, to P80 sizes as low as 7 μ m, is becoming increasingly important as mines treat ores with smaller liberation sizes. This grinding is typically done using stirred mills such as the Isamill or Stirred …

Effect of Slurry Density on Load Dynamic and Milling Performances in an Iron Ore Ball Mill - On-line Estimation of In-mill Slurry Density. Comminution Conference 2012 – Cape Town 2/9

Power load shifting was implemented on a run-of-mine ore milling circuit model. A real time optimizer and model predictive controller were used. Operating costs can be reduced for mills running below maximum capacity. At 93% of maximum throughput cost reductions of $9.90 kg can be achieved. Power load shifting is not economically feasible when there is a demand …

According to Alcoa, the world's largest producer of aluminium, the best smelters use about 13 kilowatt hours (46.8 megajoules) of electrical energy to produce one kilogram of aluminium; the worldwide average is closer to 15 kWh/kg (54 MJ/kg). Worldwide production of aluminium in 2010 was 41.4 million tonnes.

Doing metallurgical process development testwork and engineering is the best way to keep your final and total cost to a minimum.

The feasibility design throughput of the mill processing the harder primary ore was estimated to be around 400 tph compared to 700 tph for the oxide ore. However as can be seen the RHS figure below, the mill throughput for the primary ore was often as low as 300 tph –lower than the design and hence a significant business risk. Other risks ...

that the Bond CWi and the standard Bond BM Wi both recorded average values of 8 kWh/t, it was surprising that the Bond Rod Mill Wi average was 11.3 kWh/t. Since the ore is unusually soft, the Rod Mill Wi is probably irrelevant in determining required power for the SAG mill. Drop Weight Tests
