Maximizing haematite recovery within a fine and wide

Kumba Iron Ore's Sishen Mine currently produces over 3 Mt/a of -200 m iron ore, which is sent to final tailings. This material contains 50–80% by mass of largely liberated haematite, representing a mineral resource from which no value is recovered. The viable beneficiation of this material would result in extra iron ore production as well

Role of silica and alumina content in the flotation of

Mar 10, 2021Mar 10, 2021Flotation studies of naturally occurring iron ores further established the fact that it is easier to upgrade the iron values from a high silica ore compared to a high alumina ore. It was possible to produce an overall iron concentrate containing 62% Fe with 86% recovery for a silica bearing ore, but the grade and recovery of an alumina bearing

Effective Beneficiation of Low Grade Iron Ore Through

Studies carried out at the Sishen iron ore mine in South Africa have proved that the separation of fine ferrous ores was achieved by Bateman Jig .by froth flotation prior to gravity concentration. Jigging is widely used for ores andThe chemical analysis of the iron ore sample is shown in Table 1. The sample contains 56.5% Fe, which is

Froth Flotation

Froth Flotation. Froth flotation is a surface chemistry based separation process which is extensively used in the processing of mineral ore deposits as a method of separating the desired mineral component from their associated gangue material [17,34]. From: Advances in and Interface Science, 2021.

Investigations for a beneficiation route for Sishen mine's

The beneficiation of the jig slimes waste from the South African Sishen mine was investigated with three techniques to upgrade it to concentrates suitable for iron making. The slimes were first characterized by chemical, particle size and iron deportment analyses. Three beneficiation routes were then explored: reverse flotation of the as-received slimes, pre-concentration by magnetic

The influence of control and mechanical J conditions of

The jigs at Sishen Iron Ore are under bed pulsating jigs that are fully PLC controlled. All the jigs are 3 m long and the width varies from 4 m for the coarse jig, 3.5 m for the medium and 2.2 m for the fine jig. The different widths for the Jigs were chosen because of the expected PSD from the crusher circuit.
