Iron Ore Beneficiation Solutions Across Project Lifecycle. Metallurgical Testing. To be confident in investing in a project, you need to know that the separation process will work on startup and throughout the life of the operation.
For this purpose, the beneficiation of a lowgrade hematite ore fines containing carbonate minerals with magnetization roasting and magnetic separation was proposed for the first time. Therefore, the magnetization roasting of iron ore sample was studied extensively.
iron ore is expected to rise by more than 200 million tonne per year to meet the internal demand export. 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.
The lowgrade clayrich 1.0 mm fraction of fine iron ores have often proved difficult to upgrade and capital intensive to process when using traditional wet beneficiation technology including single or two stage hydrocyclone desliming, wet high intensity magnetic separation (WHIMS), spirals and final dewatering using fine screens.
The process developed basically involves crushing, classification, processing of lumps, fines and slimes separately to produce concentrate suitable as lump and sinter fines and for pellet making.
The process adopted to upgrade the Fe content of iron ore is known as iron ore beneficiation (IOB). However, Iron ores from different sources have their own peculiar mineralogical characteristics and require the specific beneficiation and metallurgical treatment to get the best product out of it.
Iron ore beneficiation is a multistage process that raw iron ore undergoes to purify it prior to the process of smelting, which involves melting the ore to remove the metal content. The process of iron ore beneficiation has two complementary goals and these define the methods used to refine it.
