The screen oversize is recycled to the ball mill. In the flotation circuit, the first stage involves bulk flotation of spodumene and tourmaline using fatty acid collector and soda ash. ... The processing plant flowsheet employed for spodumene recovery at Bald Hill is shown in Fig. 11. The run-of-mine ore is first crushed to −12 mm particle size.
Also, higher throughputs (>0.25 t/h) are recommended for complex poly-metallic flotation because these pilot plants are dificult to balance and control at low throughputs. Pilot …
This molybdenum flotation circuit, based on 250-500 tons per 24 hours is designed for low-grade molybdenum ore having high-grade streaks and with pyrite-quartz gangue.It is also basically sound for many other friable sulphide ores, such as antimony, silver and even some lead ores. The basic ideas stressed in this moly flotation …
