The evening of May 2, 1878 at the Washburn "A" mill – the largest mill of its time in the – began as any other as the day shift crews left the Minneapolis mill and the smaller night crew clocked in. But at around 7 – flour dust in the air ignited and the mill exploded.

The mill circuit consists of 1300, 875 and 500 kW ball mills. Classification of leach feed product is handled by 15inch cyclones. Free gold particles in the cyclone underflow are separated in a concentrator and sent to the gold room for direct smelting, while the remaining underflow goes back to the grinding circuit to be further reduced.
The use of gravity concentration in gold milling flowsheets is well established. In the past, a typical approach was to treat the entire mill discharge with a mineral jig. Water, necessary for classification, was added through the jig hutch. Jig concentrate was tabled to form a smeltable product.
Each milling circuit is unique, and as such the goals and most optimal control strategy might differ for individual cases. Process IQ is an expert in implementing control systems for SAG and Ball milling circuits, making use of advanced stabilisation and optimisation strategies developed by Mintek.
Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a work piece. This may be done varying direction on one or several axes, cutter head speed, and pressure. Milling covers a wide variety of different operations and machines, on scales from small individual parts to large, heavyduty gang milling operations.
concentrate is then calcined and smelted separately into gold doré. The plant was designed with a throughput of 250,000 tonnes per month. The overall plant recovery is 92%, with 40% of the gold being recovered by gravity techniques. 3 PITTOPLANT The MinetoMill® philosophy has been developed by the Julius Kruttschnitt Mineral Research Centre
Grinding in small plants, as in larger installations, has proven to be the most costly of all unit operations from both capital and operating standpoints. Therefore, grinding deserves the most scrutiny of all operations during the design procedure. A recent survey by a major grinding mill manufacturer reveals that more than 80 autogenous or semiautogenous mills having between 100 and 1,000 ...

The IGR 100 Modular Gold Processing Plant is a selfcontained fine gold recovery equipment system. It uses classification and enhanced gravity to assure you are catching the finest gold and the big nuggets. In the standard configuration material flows as follows: The miner feeds sand/gravel into the vibrating screen The screen divides your feed into 2mm plus 2 mm minus size fractions The 2mm ...
The IGR 3000 Gold Washplant was designed for a nominal 30 tons/hour feed rate based on an alluvial type material with moderate clay contamination. Material is loaded into the plant feed hopper through a static scalping grizzly with 75 mm bar spacing. Oversize is to be periodically removed manually from the grizzly. Undersize feed material is washed into the scrubber feed chute by water jets ...

be of a sufficiently fine size to facilitate acceptable gold recoveries in the CIL circuit. The mechanism of separation occurring within the cyclone is known as classification. Classification is a method of size separation of a mixture of minerals on the basis of the velocity with which the grains fall through a fluid medium (usually water).
