The ball mill work index laboratory test is conducted by grinding an ore sample prepared to passing 336 mm (6 mesh) to product size in the range of 45150 µm (325100 mesh), thus determining the ball mill work index (Wi B or BWi) The work index calculations across a narrow size range are conducted using the appropriate laboratory work index ...
Iron ore microfines and concentrate have very limited uses in sintering processes. They are used in pelletization; however, this process is cost intensive. Furthermore, the microfines of non-coking coal and other carbon-bearing materials, e.g., blast-furnace flue dust (BFD) and coke fines, are not used extensively in the metallurgical industry because of operational difficulties and handling ...
Answer (1 of 2): Iron ore exists in igneous rocks, metamorphic rocks (metamorphic rocks) or sedimentary rocks in various geological environments. Most of the environment is sediment, but many are changed due to weathering, so it is difficult to determine the source of its trigger. The most widely...

The major miners are fixated on gaining market share, and they will, but at the expense of crushing the iron ore price for years to come. Some analysts think higher-cost supply will come offline ...
The Bond work index W i is used as a measure of grindability of an ore (Deniz, 2003; Wills and Napier-Munn, 2006). The work index expresses the resistance of the material to grinding. It represents the kilowatt hours per tonne required to reduce the material from
characterisation of an iron ore resource is critical to effective project evaluation, process design, risk management and project execution. SGS collaborates with major, global iron ore producers and consistently delivers accurate metallurgical test work results. SGS has recently completed the expan-sion of its state-of-the art iron ore testing
Abstract: The Bond work index is a measure of ore resistance to crushing and grinding and is determined using the Bond grindability test. Its value constitutes ore characteristic and is used for industrial comminution plants designing. Determining the …

According to Höganäs, 2013 [10], the iron ore must have a suitable size distribution or specific surface area (m 2 /g or " Blaine index " ) to form good pellets. In some cases the ore will ...
The mineralisation is particularly soft for crushing and grinding, with a Bond work index of 6.3 and an overall comminution power requirement of 6.7 kWh/t of ore. This equates to 39 kWh/t of concentrate which is significantly less than for similar projects. The mineralisation fractures easily, preferentially along grain boundaries.

When the iron ore is extracted from the mine, it must undergo several processing stages. Six steps to process iron ore. 1. Screening. We recommend that you begin by screening the iron ore to separate fine particles below the crusher's CSS before the crushing stage. A static screen is used to divert the fine particles for crushing.
