Iron ore in the Pilbara Region of Western Australia varies in composition giving iron ore a range of densities. An accurate density figure of the material leads to accurate calculations of production throughput. Density studies of two separate iron ore mines were conducted in the Pilbara. Procedures and results are reported here._x000D_ The Pilbara Region of …

Global iron ore production was 2.46 billion metric tons (Gt) of usable ore, containing an estimated 1.52 Gt of iron, a slight increase from 2.44 Gt of usable ore in 2017. Global . iron ore production was led by Australia (900 Mt), Brazil (460 Mt), China (335 Mt), india (205 Mt), and russia (96.1 Mt).

Iron ore tailings (IOTs) are byproducts of the iron mining industry that have gained significant attention in recent years due to their potential for comprehensive utilization. This study investigates how blending steel slag with IOTs (a siliceous raw material) instead of lime (a calcareous raw material) affects slurry ing properties, …

Fine iron ore tailings slurry is commonly deposited in tailings storage facilities across the Pilbara region of Western Australia. Many of these mines process ore from a combination of deposits such as Bedded Iron Deposits (BID), Channel Iron Deposits (CID) and Detrital Iron Deposits (DID), mixing the feed to obtain the product under contract.

In this case, the high-density iron ore particles sank to the bed bottom as the iron concentrate, thereby improving the concentrate grade. However, when the gas velocity exceeded the limit, the bed became unstable because of the bubbling turbulence, which affected the density-based separation of coarse iron ore particles.

Traditional interpolation techniques in geostatistics were used to represent density spatial distribution in a block model, similarly to those used for grade estimation. This approach was developed and applied at a Brazilian iron ore mine. The results indicate MRMR are underestimated if density uncertainty is not considered.
