Pasadena-based Brazil Minerals, Inc. said Monday one of its subsidiaries has purchased a large centrifugal concentrator, which will be installed this week in one of its gold and diamond modular recovery plant in the Jequitinhonha River valley in Brazil.
With the installation of the concentrator, daily gold and diamond production can resume at the plant.
The first gold retrieval unit (GRU) built and used in the fourth quarter of 2016 could only process fine, sandy material for gold filtered by manual processing. Later, with the three additional machines, the GRU can directly process thicker alluvial material, which normally has much higher concentration of gold and diamonds.
Separation by centrifugation, now addressed with the new centrifugal concentrator, is the final step in gold recovery at the plant. In its final format, the plant will eventually have two centrifuges to double throughput.
Brazil Minerals said the factory that built the centrifuge has been in business for over twenty years and has delivered centrifugation machines to multiple gold recovery plants in Brazil, Guyana, Paraguay, Peru, and Suriname.
