Clariant Mining Solutions to reveal new collector product at Flotation ‘15

Ahead of the December issue special article on flotation, Clariant, a world leader in specialty chemicals, will exhibit and present a paper at the 7th International Flotation Conference held in Cape Town, South Africa, November 16 – 19, 2015. Clariant experts will be available to discuss the company’s broad line of flotation and collector products, including the revolutionary new Hostaflot® products for copper mining.

Clariant’s Jacques Bezuidenhout, Senior Mineral Processing Engineer, will present the paper, Clariant collectors for use as alternatives to xanthate collectors in traditional sulfide flotation applications. In powder and pellet form, xanthates have been an industry staple for the collection of sulphide minerals for more than 90 years. However, in today’s market, they pose health risks to workers, present disposal challenges to mining companies, may require additional infrastructure for handling, and are classified as a fire and explosion hazard.

Clariant Mining Solutions developed several new technologies in its Hostaflot line of collectors which are effective alternatives to hazardous xanthate collectors. During Flotation ’15, Bezuidenhout will review the results from Clariant’s extensive lab development trials of the new collectors and discuss how the new Clariant products are a safe, cost-effective alternative to xanthates.

“This is groundbreaking new collector technology for those operations mining copper,” says John Gordon, Global Head of Clariant Mining Solutions. “With the Hostaflot products being shipped and dosed in liquid form, they offer a high flotation performance and a safer handling and disposal solution than xanthates, can lower the capital expenditures for mines to convert powdered xanthate into a liquid solution, and provide a longer shelf life than solid xanthate. At a major copper/molybdenum mill in South America, one Hostaflot product has been approved as a primary collector, with similar metallurgical results in terms of recovery, grade and selectivity against SIPX.”
