The Power of Bazin-Production Forecasting with the Bazin
Back in 1994, Claude Bazin presented a novel method for linking size data from milling models to the feed input of flotation models. It was achieved with the simple addition of a metal/mineral distribution—size distribution relationship. This allows grade and recovery predictions from a varying mine plan via product size distribution predictions. This paper presents a case study …

The evoluation of copper flotation plant performance by …
Mass balancing studies were performed using JKSimmet software. Mass balance results provided the flow rates and the chemical assays around the circuit. Therefore using the flow rates around each stream, the recovery of every unit in the circuit was calculated. The laboratory flotation tests were performed to obtain the optimum flotation conditions.

Probabilistic methods for flotation circuit mass balance …
Flotation control and supervision allow flotation circuits to maintain target concentrate grades and plant recoveries. The decision-making required for effective supervision of flotation control systems (e.g., selection of targets, setpoints, and setpoint limits) is enhanced by up-to-date information on total and component mass flows throughout the circuit.
