Magnetic separation is the most efficient separation method of these technologies. Modern magnetic separators are capable of processing up to 500 t ore/h per unit at a very low operating cost (0.3–0.5 kWh power and 2 m 3 recyclable water/t feed ore). Flotation has the advantage of good selectivity, but often it has much higher operating …

As rare earth metal prices fall, the low-cost beneficiation of their minerals has become essential. Flotation-magnetic (FM) separation is a newly-developed technology for the economic recovery of rare earth elements from the Dalucao ore. The FM process selectively agglomerates the rare earth particles while separating them from …

Titanium beneficiation production line Gravity separation. This method is suitable for the first concentration or pretreatment of crushed titanium ore. By gravity separation, we can separate most of the gangue minerals with a density less than 3g/cm 3 from titanium-containing minerals with a density generally greater than 4g/cm 3.

3.11.2.5 Magnetic Separation. Magnetic separation is a process where a contaminant is first attached onto a magnetic carrier material (e.g., magnetite), and subsequently, the contaminant-laden carrier is separated under a magnetic field. The simplest magnetic separator is a permanent magnet.

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.

Magnetic separation technology plays an important role in upgrading such low-grade iron ores, because the magnetic separation process possesses the combined …

Hematite ore's magnetic characteristics were significantly impacted by magnetizing roasting. By selectively magnetizing roasting, hematite is transformed into magnetite. With an Fe grade of 65.25% at a recovery value of 72.5% in the concentrate, magnetic separation produced the greatest result for Fe.

The Wetherill separator type is still in use today in various forms for separating precious metals, typically after calcination of ore feed. Use of magnetic separator to recover gold-bearing iron oxides from roaster leach tails is also practiced such as at Barrick's Goldstrike operation (Douglas and Semenyna 2013).

Magnetite is a strongly magnetic mineral, so a beneficiation process based on weak magnetic separation is generally used in magnetite beneficiation. According to the nature of iron ore and the characteristics of the beneficiation process, it can be divided into the following processes.
