the downstream process (Laplante, 2000). The use of batch centrifugal gravity recovery and flash flotation operations in a closed loop milling circuit may be an option for reducing the circulating load and processing complex ores containing both liberated (or ''free'') gold as well as gold in a sulfide matrix (unliberated or refractory).

Development of a laboratory method to predict plant flash flotation performance. Flash flotation cells are increasingly being employed to recover valuable material present in the grinding circuit, reducing the potential for overgrinding and enhancing plant performance with the added advantage of reduced capital outlay and operating costs.
