Improving recovery of iron using column flotation of iron

Nov 01, 2020 Column flotation tests were performed with iron ore slimes. The column having 5.1 cm in diameter and a total height of 6.0 m was used. The %s in the conditioning phase and in the column feeding were kept at 35% and 25%, respectively. The pH adjustment was made with sodium hydroxide.

Column reverse rougher flotation of iron bearing fine

Sep 01, 2020 The use of these new reagents may bring an innovative concept of iron ore and tailings reverse cationic flotation without the need of using starch as iron oxides depressant. Herein, this higher selectivity allowed a peculiar separation of iron and siliceous concentrates in a single rougher operation, without the employment of starch as depressant.

Reverse column flotation of iron ore SpringerLink

The use of column flotation was considered for the “reverse flotation” of iron ore, where the gangue (quartz) was recovered in the froth product. This use of the froth for carrying the gangue mineral rather than carrying the valuable concentrate significantly changes the operational requirements of the column. The objective of this work was to determine which of several column flotation

The second and third columns are quality measures of the iron ore pulp right before it is fed into the flotation plant. Column 4 until column 8 are the most important variables that impact in the ore quality in the end of the process. From column 9 until column 22, we can see process data (level and air flow inside the flotation columns, which
