Ilmenite Beneficiation Test Process. At the beginning of the process, classify the ore particles by a thickener to distinguish between coarse-grained and fine-grained ores. Coarse ore is classified into fine-grained ore and tailings by gravity separation. The cost of gravity is low with small environmental pollution.
The primary ilmenite developed industrially is a composite deposit containing iron and titanium. The ore dressing process is divided into two parts: iron beneficiation and titanium beneficiation. The raw material of the titanium dressing plant is tailings from iron dressing. Titanium separation methods include gravity separation, …
The beneficiation of ilmenite, the preferential removal of the iron oxides by selective chlorination, has been studied in a fluidized bed reactor. Temperatures from 700°C–950°C, inlet mole ratios of carbon monoxide (the reducing agent used) to chlorine (the oxidizing agent used) from 1–2, and a wide range of values of the ratio of initial ...
