Screw-Spiral Classifier: Select, Size & Install
The size of mechanical classifier required for a particular job depends on the following factors: Tons of dry solids to be overflowed per 24 hours. This is simply a predetermined tonnage. Mesh size at which separation is to be made. The mesh size is determined by laboratory tests or is already known from previous experience. […]
Hydroclassifier
Hydroclassifiers are solving the most difficult fine sizing and desliming problems by combining high metallurgical efficiency in a rugged, well- built machine to accurately fulfill the exacting conditions required. Accurate separations can now be made in the 100 mesh range and finer. This fine separation requires considerable classification area per ton as well as minimum […]
Gold Ore Roasting Plant
To achieve optimum gold recovery from the certain sulfide ore body, the ore must be finely ground to achieve proper oxidation and mineral separation. The ore is separated into stockpiles after it has been mined. These stockpiles are based on gold content, sulfide content, and carbonate content. The ore is blended prior to being fed […]
Eskay Creek Mill Process Description
The Eskay Creek Mine is located in north-western British Columbia approximately 83 km north-west of Stewart, B.C. as shown in the location map Figure 1. A restricted access 59 km long gravel road, shown in Figure 2, from Bob Quinn Lake junction of highway 37 provides road access to the site. The employees at the […]
Vibrating Screens in Mineral Processing: Types and Advantages
Vibrating Screen SPECIFICATIONS The driven sheave and balance wheels are on the center line of the shaft. The shaft supports no other load and is subjected to no flexing or bending, and rotates freely on its central axis. The driven sheave can be mounted on either end of the shaft depending on whether a right […]
Types of Speed Reducers
The Speed Reducer eliminates unnecessary transmission equipment, thus providing compact drives, and assures positive performance. It is made with speed reduction ratios up to 4,000 to 1 and with right angle (vertical or horizontal), or parallel shafts for either light or heavy duty. The information which follows gives applications and other pertinent data on the […]
Centrifugal Pump
Centrifugal Sand Pump The Nor-Sand Centrifugal Sand Pump is an evolution in pump design which overcomes the many difficulties encountered in handling abrasive materials. An unimpeded flow of pulp to the impeller is assured, as provision has been made to prevent coarse material from settling out by providing the pump with a central inlet on the […]
Cyanide Pre-Leach Conditioner
The notably successful application of flotation to many cyanide ores, and the development of a plant to treat the flotation concentrates by cyanidation, makes it possible for small plants to increase their recovery greatly and to make a much wider margin of profit. These concentrate treatment plants do not require large outlays of money and […]
Portable Gold Processing Plant
Portable Gold Amalgamation Plant Free milling gold and silver ores are efficiently and economically treated in Amalgamation Mills. These mills are often used in the early stages of development of free milling gold properties to recover the main portion of the gold with a simple, inexpensive flowsheet. Later a more comprehensive installation can recover the […]
Mechanical Automatic Gold Panner
Mechanical Concentrating Pan, although primarily developed for the recovery of placer gold, is proving equally successful for treating mine dumps, old mill tailings, and values from low grade sluice operations. The Mechanical Concentrating Pan has also proved valuable as an amalgamator in free milling gold plants. The phenomenal success of this unit is based upon […]
