The calculation formula for the loss rate is: ... The current common iron ore blending methods only refer to the mixed ore indicators and the original ore's nature, but ignore the impact of the mixed ore properties on the beneficiation production. They often regard ore blending and beneficiation as two separate processes, rather than using ...

The determination of reduction degree in a DR process is sensitive to the total iron in the ore and DRI. An accurate and high throughput analysis method for total iron has been developed.

Abstract. A method is proposed for calculating the stress in roasted zonal fluxed pellets. The method is based on the appearance of a stress state at the boundary zones with different solidification temperatures of the slag inclusions on cooling. The stress state is calculated for Kachkanar pellets with different positions of the hematite and ...

We can represent this as shown in Figure 3.2.15 by including the waste within the one ton of mined ore. This waste material effectively reduces the copper in the block by the amount of the dilution. Let's assume an average dilution of 5%. The copper present in the mined block of ore is reduced by 5%, to 19 lb of copper.

The equilibrium diagram of iron oxides, hydrogen and carbon monoxide (Figure 4) shows the equilibrium gas composition to reduce iron ore. Thermodynamic calculations have shown that CO has a higher reducing ability at lower temperatures, whereas reduction by H 2 is more thermodynamically stable at higher temperatures [ 29 ].

Bond impact crushability work index (CWi) ( Bond, 1963) results reported for iron ores vary from hard iron ore (17.7 kWh/t) to medium hardness iron ore (11.3 kWh/t) and friable iron ore (6.3 kWh/t) ( Table 2.11; Clout et al., 2007 ). The CWi for hard iron ores typically overlaps with those reported for BIF ("taconite") iron ores while the ...

C = F/K = F (f — t) / (c-t) = the weight of the concentrate. Recovery %. Represents the ratio of the weight of metal or mineral value recovered in the concentrate to of the same constituent in the heads or feed to the process, expressed as a percentage. It may be calculated in several different ways, depending on the data available.

The area influenced by any given hole is found as follows: (1) Divide angle at hole by 180°. (2) Multiply total area of entire prism by above result. (3) Multiply area found by (2) by the average thickness (found by solution of the formula) of ore in the hole, which thus transforms this smaller prism into volume.
