Mill And Cyclone Optimisation Projects

The overflow will target an 80% passing product size of 10 µm. The cyclone overflow reports to the silver-lead cleaner circuit, while the underflow flows by gravity to the regrind mill. The regrind mill uses ceramic media with a 2-3 mm diameter and mill discharge also reports to the silver-lead cleaner circuit. Silver-Lead Cleaner Flotation

The conversion to closed-circuit milling entails replacing the two tertiary cyclones with a cluster of cyclones that will classify the mill discharge, together with the primary and secondary cyclone overflows. The coarse cluster underflow will report back to the mill and the finer cyclone overflow to a new 45-metre diameter high-rate thickener.

Computational Fluid Dynamics (CFD) based optimisation of a combined spiral jet mill and cyclone. Some combined spiral jet mill and cyclone designs have poor cyclonic separation yields, and this thesis presents the CFD and experimental investigation which led to an optimised mill and cyclone that significantly

mill/hydrocyclone cluster system is installed on the common system components. Typically these measurements include hydrocyclone feed flow, feed density, manifold pressure, sump level, etc. Determining the exact source of the oversize can be a complicated and time consuming process for a busy operations crew.

Developed and published methodology for grinding circuit cyclone selection (for new installations) and optimization (of existing installations). Carried out numerous projects to measure and optimize the performance of plant pumping/cycloning operations, including inclined cyclones, two-stage cycloning, and high-efficiency cyclones.

The grinding mill might be the issue. Of course, the hydrocyclone isn't the only place to look when you are reviewing the classification of your grinding mill circuit.. Often when we're investigating a mill circuit, there are cases where the amount of new feed to the plant has exceeded the ability of the mill to grind the ore fine enough to allow the cyclones to generate …

The optimisation project had delivered a mill that should have been set up for success. The control system had full DCS functionality and the following additional instrumentation had been added: SAG Control - December 27, 2005 100 110 120 130 140 150 160 170 180 04:48:00 09:36:00 14:24:00 19:12:00 00:00:00 04:48:00 09:36:00 Time Tonnage - mtph 4300

The ECS/Process Expert further optimises the balance of the grinding circuit to consider critical parameters such as mill sump level and dilution water addition and cyclone operating pressure.

Figure 6: Mill Optimisation Control Strategy. MillSTAR. THROUGHPUT OPTIMISATION. SEGREGATED ORE FEED CONTROL (Feed Ratio Optimisation) On milling plants fed by a segregated feed supply, such as a stockpile, the varying size and hardness of the mill feed material affects the residence time in the mill and the power drawn.

MILL THROUGHPUT OPTIMISATION . Obtaining optimum power usage from a mill is highly process-dependent. MillStar's Power Optimiser dynamically determines the optimum operating point for the mill and controls the mill to maintain the power. A number of safety checks are also present to substantially reduce the number of mill overloads.

Cyclone underflow will report to the ball mill feed for further grinding. Mill circuit cyclone overflow at a target grind of 80% passing 75µm will gravitate to a pre-leach thickener. Lime will be added to the SAG mill feed via a silo and variable speed feeder. Provision has been made for a ball loading system for both mills.

Cyclone underflow contains the greatest opportunity for gravity concentration since it is the highest grade. (Please refer to flowsheets included.) Recovery across the enhanced gravity device will be improved by the absence of slime. Free gold that escapes from grinding circuits via cyclone overflow will all be recovered by
