Welcome to KIOCL. KIOCL Limited (Formerly known as Kudremukh Iron Ore Company Limited), a Flagship Company under the Ministry of Steel, Govt. of India was formed on 2 April 1976 for mining and beneficiation of low grade iron ore at Kudremukh, Karnataka, India.KIOCL has been a pioneer with over four decades of experience in operating Iron …

for mechanical sampling, manual sampling and preparation of samples taken from a lot under transfer. This is in order to determine the chemical composition, moisture content, size distribution and other physical and metallurgical properties of the lot, except bulk density obtained using ISO 3852 (Method 2).

A standard operating procedure, or SOP, is a set of detailed instructions that describe how to perform a process. Read on to find out how to make your own SOPs

The received iron ore sample is amenable to upgradation through beneficiation to get pellet grade concentrate. The beneficiation process was established, involving crushing, screening, jigging, spiral separation, size reduction, desliming and magnetic separation.

This additional requirement of iron ore will need beneficiation of low grade ore/fines to get the major portion of increased demand. This paper deals in brief to use of available methodologies for beneficiation of iron ore in Indian context.

In general, iron ore beneficiation is done at the mining site. The concentrated iron ore is subsequently sintered or pelletized, depending on the grain size distribution, before it is charged to an ironmaking plant. In cases where after the initial processing steps the iron ore fractions are of inferior quality (too fine or low iron content ...

Non-metallurgical bauxite ore is generally sold at higher prices, and consequently can offset lower recovery and higher beneficiation costs. The primary objective of beneficiation for non-metallurgical bauxite is to lower iron and titanium contents in the product, and also to enhance alumina values.

These iron values can be recovered by further beneficiating the fines, slimes and tailing by selective flocculation, which is defined as the selective agglomeration of iron ore particles using ...

Iron and Steel industry plays a vital role in the Indian economy. At present, iron ore of around +64% Fe is used for production of iron through blast furnace and direct reduction (IBM 2019). To produce +64% Fe from low- and medium-grade ores, crushing and washing are compulsory. During washing of iron ore, to improve the quality of …

The iron-making process requires high-quality raw materials, with Fe ≥ 64% and <2% alumina and silica each, to enhance blast furnace productivity at a given energy consumption rate. There is a ...

Iron ore beneficiation is the process of improving the quality of iron ore by removing impurities and increasing its iron content. It is necessary to reduce alumina and silica in the feed. The process improves the chemical, physical, and metallurgical characteristics of the ore to make it a more desirable feed for iron-making furnaces.

Mineral beneficiation begins with crushing and grinding of mined ore for near-complete separation of ore and gangue minerals as well as between ore minerals. Each processing step is designed to increase the grade (concentration) of …

Mohanty and Das (2010) investigated the modeling of hydrocyclone-based slime upgrading using sodium hexametaphosphate as a dispersant for iron slimes at Indian iron ore mines.

of good grade ores. It is imperative to use low grade iron ores to meet the current demand. In the Jharkhand-Odisha belt hematite ore containing significant amount of goethite material have difficulty in processing. In the present paper, response of a low grade hematite-goethitic iron ore to beneficiation for the production of sinter and pellet feed material …

This chapter introduces the principle of how low-grade iron ores are upgraded to high quality iron ore concentrates by magnetic separation. Magnetite is the most magnetic of all the naturally occurring minerals on earth and can be readily extracted by low-intensity magnetic separators from magnetite ores. On the other hand, oxidized iron …
