Investigation of the effect of the reagent suite in froth flotation of a Merensky ore
… routes owing to the depletion of high-grade ores, and the ever increasing demand for precious metals for a wide range of applications. The valuable minerals, PGMs (Platinum Group Minerals) and BMS (Base Metal Sulphides) in the ores are extracted through the aid of chemical reagents …

The effect of polysaccharides and inorganic dispersants on the surface characteristics of talc and the effect on the flotation performance of a Merensky ore
… how this relates to the flotation performance of Merensky ore. The rationale in investigating the talc changes are due to its naturally flotable nature and the downstream problems that result from its reporting to the concentrate causing difficulties disproportionate to its average concentration …

The effect of copper sulphate on froth stability
… operations. This was done on two PGM containing ores namely Merensky and UG2 (Upper Group 2) ores from the Bushveld Complex of South Africa. The dynamic froth stability factor (Σ) and froth half life time (t1/2) were used as measures of froth stability. These were obtained using a froth stability …

Developing a framework for the design of the milling and rougher circuits for a platinum-bearing UG2 ore
… platinum is mined predominantly from two reefs – Merensky and UG2. Most of the platinum group minerals (PGM’s) in Merensky ore are associated with base metal sulphides (BMS), and thus Merensky concentrators will usually resemble simple BMS circuits. However, the mineralogy of UG2 ore is more …

A quality control model for the development of high-confidence flotation test data
… laboratory scale flotation test data for the Merensky ore type found in the Bushveld complex of South Africa. The complex nature of the platinum-group element (PGE) deportment in this ore renders the normally-practiced procedures inappropriate for this particular testwork. A more robust and …

The application of a machine vision system to relate to froth surface characteristics to the metallurgical performance of a PGM flotation process
… the use of a machine vision system to explore the relationships between the structure of the flotation froth surface, flotation performance and selected operational parameters in a flotation operation aimed at the beneficiation of Platinum Group Minerals. The machine vision system employed …

The effect of flotation reagents on the coagulation and dewatering of flotation tailings
… reagents on flotation selectivity. Utilising Merensky ore from the Bushveld Igneous Complex (BIC), this study examines how flotation reagents, including coagulants, flocculants, depressants, and collectors, affect the coagulation and dewatering of flotation tailings. The BIC has 75% of the …

The role of nitrogen on the flotation performance of a complex sulphide ore
… on flotation performance of a sulphide PGM ore. Merensky ore obtained from Impala Platinum mine, Rustenburg, was used in laboratory batch flotation tests. Nitrogen addition was implemented during the conditioning and / or flotation stages of the test. In order to further evaluate the …

An investigation into the relationship between electrochemical properties and flotation of sulphide minerals
… recovery by flotation of minerals found in the Merensky reef, which is one of the major reefs in the Bushveld complex. In that reef, base metal sulphide (BMS) minerals are commonly associated with PGMs and this has an effect on the way in which these minerals are concentrated by flotation …

The interactive effect of depressant type and dosage with frother dosage in the flotation of a PGE ore
… of the platinum group element (PGE) bearing ores of the Bushveld complex in South Africa constitute between 1 % and as little as 0.1 % of the total mass. In the processing of these ores by flotation, the naturally hydrophobic talc minerals cause over stable froths. The drainage of liquid and …

Water Quality Impact on Flotation Response: A Focus on Specific Ions and Temperature
… Literature also highlights that different ores and different minerals react differently to temperature variation. The presence of certain species in process water with water variation has been seen to impact the flotation response. It stands to reason that simultaneously varying the …

Investigating electrolyte-reagent-mineral interactions in response to water quality challenges in the flotation of a PGM ore
… and unwanted gangue minerals contained in an ore. It utilises the differences in surface properties of the minerals to be separated. Among other factors affecting flotation, water is a major factor as it acts as a reagent and transport medium. Therefore, it stands to reason that the quality of …

A determination of the effect of changing collector chain length under varying Water Quality
… of synthetic plant water. Batch f lotation on a Merensky ore was utilised to obtain copper and nickel grades and recoveries which illustrated flotation performance. Additionally, batch flotation was used to obtain the entrainment factors of the two collectors at the different ionic strengths of …
