Processing is the stage that typically follows grinding, if the application calls for it. In this phase, minerals have been crushed and ground, and are fed into flotation cells, thickeners, aggregated tanks, clarifiers, and filters where chemical reagents and agitation are used to extract and concentrate the target element or product. Tailings, waste rock, are then pumped into dewatering equipment such as a filter press, belt press, or centrifuge, after initial dewatering in a thickener and/or clarifier. Agitators, mixers, and tanks are commonly needed in this phase to properly mix slurry and reagents.
As a worldwide supplier of mineral processing equipment, D’Angelo International is uniquely poised to supply new, surplus, rebuilt, or used mineral processing equipment for your operation. This equipment is critical for the production of base metals, and precious metals disseminated into sulfides, tellurides, or other less common anions. Additionally, processing is useful for separating minerals or elements with significant differences in density, solubility, reactivity, or other physical properties.
