Engineering

Our process design and equipment sizing methodologies are based on state-of-the-art geometallurgical mapping, extensive auditing of SAG and AG mills, ball mills, HPGR circuits, and flotation circuits, comprehensive flotation models that are among the most advanced in the industry, and some good, old fashioned, operating experience.

Our process development philosophy is simple: the process should be designed for the highest economic return that satisfies the strategic interests of the owner. Our advanced modeling and geo-metallurgical methods employ an iterative procedure that allows us to select the key equipment and process characteristics such that the net of capital and discounted future costs and earnings are maximized.

Geometallurgy

Aminpro Chile provides guidance in the development of geometallurgical models and will assist mining companies in the development their own process models (based on geometallurgy) to forecast production levels. These same models can be used for plant design and optimization.

Crushing / HPGR

We have designed, modeled, and operated many high-capacity crushing and HPGR concentrators. Our advanced models provide machine capacity and product size distribution for traditional jaw and gyratory crushers. We use the Morrell/JK approach to HPGR modeling and have extensive databases of circuit audits and equipment costs. We also have extensive operating experience with HPGR and traditional crushing circuits in hard rock mining.

Grinding

Our grinding mill sizing methodology is not based on textbook equations, but on hundreds of industrial audits on almost every kind of grinding circuit. Our audit-based models include the following unit operations: Rod Mills / Ball Mills / Verti Mills / Cyclones.

Flotation

Our flotation model is based on size-by-size collection and entrainment kinetics combined with a froth recovery model. The result is a robust and reliable model that can generate grade-recovery curves for a range of ore types and operating conditions.

Dewatering

We have extensive experience in the design and operation of traditional thickeners, high-capacity and paste thickeners, tailings dams, filters and slurry pumping/ transport systems. We have built relationships with vendors, third-party consultants and other experienced subject matter experts to ensure that your dewatering and tailings impoundment facilities are optimized.
