ANALISIS KEHILANGAN (LOSSES) MAGNETITE PADA …

The dense medium separation process used in most coal washing and magnetic separation plants requires a suspension of finely milled magnetite in water. Magnetite for coal washing must be of overall high purity and be devoid of contaminants, such as …

Magnetite is our core business

Magnetite heavy media processes are accurate, efficient and easy to control separators, capable of producing high quality clean coal. Magnetite recovery circuit operation and magnetite consumption are the main reasons for high capital and operating costs.

Coal Washing, Magnetic Separation & Processing

A systematic study through laboratory tests and a detailed plant sampling campaign helped in identifying the causes of magnetite loss. Upon implementation of the recommendations, the magnetite losses decreased, resulting in a saving of approximately US$27,500 per annum.

Magnetite Uses

Untuk mendapatkan 1 ton clean coal pada washing plant PT. Kaltim Prima Coal menggunakan 0,7 kg media berat (magnetite). Namun penggunaan magnetite pada tahun 2016 lebih dari 0,7 kg yaitu rata-rata 0,9 kg/ton untuk mendapatkan 1 ton batubara. Berdasarkan hal tersebut maka perlu dilakukan analisis kehilangan magnetite pada washing plant batubara.

Sep 01, 1991· For magnetite, with a solid specific gravity of 5.0, this concentration works out at a maximum suspension specific gravity of 2.3. This is well above the operating specific gravity used in coal washing. Because of its comparatively low cost, magnetite is commonly used in the dense medium suspensions in coal preparation.

Magnetite Iron Oxides

In coal preparation, the mineral magnetite (FeO, Fe 2 O 3) has become the most commonly used material, not only because it fulfils all the above criteria, but also because of its worldwide occurrence either as an iron ore or as a by-product of mining operations for other minerals. Like any mineral, magnetite rarely occurs in the pure state and ...

Coal Beneficiation

The magnetite extraction plant is a $60m component of the $600m EHM life-of-mine extension project. The development included the underground mine and magnetite processing operations. The recovery of magnetite from the existing tailings stream will allow EHM to diversify its product mix and become an iron ore producer.
