Johannesburg, Friday 03 November – Clariant, a world leader in specialty chemicals to the mining industry, is pleased to announce its participation in the 8th International Flotation Conference (Flotation ’17) taking place on the 13th November to the 16th at the Vineyard Hotel, Cape Town, South Africa.
Clariant Metallurgist for Sub-Sahara Africa Mining Services, Linda Mahlangu is set to present a research paper, A Review of Phosphoric Acid Esters for the Flotation of Oxidised Copper Minerals on Tuesday, 14th November at 11:00. This paper follows a research study conducted focusing on phosphoric acid esters as potential alternatives to the sulphidizer-xanthate method currently used by most operations to recover oxide copper. In conjunction with the presentation, technical experts and commecial leaders will be available at the Clariant Mining Solutions exhibition stand while showcasing Clariant Southern Africa’s strengths in froth floation and mineral processing.
Low grade oxide copper mineral flotation dates back to almost 70 years. Over the years the use of fatty acids to concentrate the copper oxides lost its popularity with most operations preferring the controlled potential sulphidisazition (CPS) method. In the presentation to be given by Ms. Mahlangu, she will deomonstrate the use of phosphoric acid esters as alternative collectors for oxide copper mineral flotation. Phosphoric acid esters are generally used in the flotation of oxides of iron, titanium and tin. These specialized collectors are also effective in selectively floating carbonates in the reverse flotation of phosphates, and since malachite is a carbonate mineral, in theory these collectors will effectively recover copper oxides. Clariant Mining Solutions has embarked on a campaign to review these collectors as alternative collectors for oxide copper flotation. The flotation performance obtained with three such collectors is discussed in this paper.
