Aug 26 2020 The grinding hub is generating a completely new product known as GF88. According to Vale GF88 is a high-grade ground iron ore fine that uses the companys flagship Caraj s Fines as raw material. It provides an eco-friendly solution for pellet production.

A novel direct reductionflash smelting separation process

A novel direct reductionflash smelting separation process

Jan 02 2021 Too fine iron ore particles will cause difficulties in the subsequent grinding-magnetic separation process and easily cause slag‑iron mixing which will affect the yield of iron and the effect of dephosphorization. It is necessary to select an appropriate ore particle size range according to different process conditions.

Hydrogen Reduction of Hematite Ore Fines to Magnetite Ore

Hydrogen Reduction of Hematite Ore Fines to Magnetite Ore

Surplus coke oven gases COGs and low grade hematite ores are abundant in Shanxi China. Our group proposes a new process that could simultaneously enrich CH 4 from COG and produce separated magnetite from low grade hematite. In this work low-temperature hydrogen reduction of hematite ore fines was performed in a fixed-bed reactor with a stirring apparatus and a laboratory Davis magnetic .
