It is crucial to selectively remove iron impurities during the titanium production process. The present study investigated the acid and flux fusion digestion techniques for complete dissolution of ilmenite and subsequent separation of iron and titanium by precipitation process. Analytical results indicated that the Na 2 HPO 4 /NaH …
Titaniferous magnetite hard rock deposits are common throughout the world. Previously they have been processed to recover vanadium using the standard salt roast process, however the economics based on vanadium alone can be marginal due to the high CAPEX and OPEX, making it vulnerable in a volatile vanadium market. New Zealand Steel and …
A high-titanium slag with 85.32% titanium was obtained by the iron powder induction leaching and alkali leaching. Additionally, the additive (NH4)2SO4 could be recycled, achieving zero emission of ...
Before being used as a raw material for ironmaking, the iron sand must be upgraded by magnetic separation to increase the concentration of the iron as well as …
1. Introduction. With the continuous exploitation of oil and gas fields, the rock structure of the reservoir is destroyed due to the low rock strength or the unreasonable exploitation method [1] and operation method. This finally leads to the existence of sand production [2], [3].Although sand production is a common phenomenon in the production …
