Clay minerals, rain, and seawater all contain K. There are sizeable potash-bearing rock deposits in many regions of the world originating from minerals in oceans that evaporated millions of years ago, with significant deposits in Western Canada and Eastern Europe. Most potash fertilizer comes from one such potash rock, sylvinite, which requires separation from salt and other minerals and suitable preparation for use in fertilizers.
Conventional underground and solution mining is the most common potash mining method used today to extract potash from rock deposits. Once the potash is extracted, producers rely on potash flotation to maximize mineral grade and recovery. During potash processing, flotation reagents are used to introduce air bubbles to which the potash can attach and rise to the surface for collection. Flotation reagent selection is key to maximizing the amount and purity of the potash recovered.
Arkema custom-formulates potash processing chemicals based on the specific properties of each potash deposit to maximize mineral grade and recovery. Our potash processing product line includes flotation reagents, float oils, frothers, pH modifiers, defoamers, flocculants, and anti-caking coatings specifically developed for the potash production process. Our technical experts also provide process consultation and flowsheet design to optimize your potash production process and product quality. Let us help you maximize the potential of your potash deposit and production process.
