(October 2018)

Maelgwyn Mineral Services (MMS) has won contracts to supply two more Imhoflot pneumatic flotation plants to potash projects for JSC Belaruskali in Belarus. Working with its engineering partner, NPO Passat, one of the plants will replace existing conventional flotation at the Belaruskali “Plant 3” whilst the second plant will be for the new Petrikov greenfield project. The contracts cover the supply of 16 Imhoflot V-Cells. Each cell capable of processing up to 760 m3/h / 150tph. Imhoflot pneumatic flotation offers higher selectivity than conventional flotation and improved project economics. The equipment is being delivered in stages, commencing in November 2018 with the final delivery in mid-2019.

The contracts continue the long-term technical relationship between JSC Belaruskali and MMS going back to 2005. Since that time MMS has been instrumental in assisting the company in upgrading all its process plants from conventional to Imhoflot pneumatic flotation.

JSC Belaruskali is a state-owned company and one of the world’s biggest fertilizer suppliers. It produces approximately 15% of the world’s potash fertilizer the majority of which is beneficiated by the flotation process. NPO Passat is a Belarus based engineering company who specialise on the design and manufacture of process equipment, including executing turn-key projects. They have used their world class experience to deliver numerous projects in raw materials processing and enrichment.

In addition to its applications for industrial minerals there has been considerable recent interest in the use of Imhoflot pneumatic flotation in processing the so-called “battery metals” and including graphite. The higher selectivity offered by the hi-energy flotation system together with its small footprint, flexibility of operation and lower capex/opex offers considerable advantages over conventional flotation in this rapidly changing and competitive market segment. MMS, through its subsidiary MMSA, can offer project evaluation to DFS level at its world class laboratory and pilot plant facilities in Johannesburg, South Africa.
