Process air is supplied to the process by two 150 HP, 1200 nm3/hr, 250 kPa compressors. Each compressor is a totally self-contained package. Each compressor is an electric motor driven, single stage screw compressor complete with accessories piped, wired and baseplate mounted. Under normal operating conditions only one of the two compressors will be used. … Read more
Introduction to an EXAMPLE Fresh Water System Water is pumped from the fresh water well to the camp tank which provides pressure and storage capacity for the camp. The camp distribution system is located between the well and the camp tank, such that the pipe between the camp and the tank may have flow in … Read more

Detailed Process and … Read more
EXAMPLE Operation and Preparation for Start up Ensure the mill is prepared to start up at the design throughput and range of solids content. Walk the tailings line to check for damage to the pipe or overhead wires. Open the sluice gate at the tailings spillage diversion. Ensure the tailings box is free of obstruction. Ensure … Read more
EXAMPLE Tailings System Tailings from the processing plant are collected in a common tails box and flow by gravity to the tailings pond. The tailings flow at a rate of 51.6 cubic meters per hour and 34% solids. The tailings line consists of five separate sections and each individual section is designed to suit its local topography. … Read more
The following flotation reagent mixing system is typical for the flotation reagent mixing systems: A-208, Xanthate and Sodium Silicate. The reagent mix tanks, for the above mentioned reagents, are located on the basement floor. Feed chutes from the main operating floor carry dry or wet reagents to each mix tank. Either reclaim or fresh water is … Read more
A Flocculant like the Dry polymer (Percol 156) is used throughout the process to flocculate fine particles and increase the solids settling, filtration and clarification rates. Flocculant is prepared and aged in the skid mounted automatic flocculant mixing system. A control panel for the system is mounted on the same skid. Refer to the equipment manufacturer’s … Read more

The lime system is equipped with its own PLC which automatically provides lime slurry for the process. Hydrated lime is stored in a … Read more
VARIABLE RANGE EFFECT ON PROCESS Crushing Jaw Crusher Close side setting 3″ plus H – Material too large for cone crusher. N – 3″ L – Reduction in capacity. Excess power draw. Cone Crusher Close side setting 3/8″ – 1″ H – Increased circulating load of screen and cone. N – 1/2″ L – Increased power consumption, decrease … Read more
In our EXAMPLE precipitate from the – Zinc Precipitation Circuit will be considerably wet and therefore it must be dried prior to entering the induction furnace. Excess moisture in the precipitate essentially wastes energy; as energy is required to evaporate the water before the precious metals and fluxes are melted. In addition, water not only wastes energy … Read more
