Introduction. India is rich in iron ore deposits and is the fourth largest useable iron ore producer globally as of 2019–20. As per the Steel Policy 2017–18, around 450 MTPA (million tons per annum) of high-grade iron ore resources are required to meet the steel demand of 300 MTPA in 2030, shown in Fig. 1.

Estimated to involve an initial cost of R35m (£1.65m), the proposed plant will be located in Ironveld's Lapon mining area. It will have a maximum capacity of about 27,000 tons a month of DMS-grade magnetite, based on a design throughput of 60 tons an hour. The plant will comprise screens, crushers, a mill and a low-intensity magnetic separator.

The separation results indicate that the cDMS separator is capable of producing a high separation selectivity for magnetite powders. For feed particle size below 0.10 mm, the iron grade of magnetite in concentrate reached 43.07% at 98.38% recovery for magnetite, with the iron grade of magnetite in tailings significantly reduced to 1.33%.

The principal separation in iron ore beneficiation, therefore, is between the iron minerals, hematite and/or magnetite, and silica, principally in the form of quartz. The use of flotation, either alone or in combination with magnetic separation, has been well established as an efficient method for rejecting silica from these iron ores.

In many lithium ore beneficiation plants, it is a common practice to de-slime the ore prior to flotation. De-sliming is typically carried out to remove the −20 µm size fraction to improve selectivity of separation because slimes are detrimental to the flotation circuit (Bale and May, 1989). As is the case in many operations, de-sliming is ...
