Copper Flotation
Although basic porphyry copper flotation and metallurgy has remained virtually the same for many years, the processing equipment as well as design of the mills has continually been improved to increase production while reducing operating and maintenance costs. Also, considerable attention is paid to automatic sensing devices and automatic controls in order to assure maximum […]
Copper LPF Leach Precipitation and Flotation Process
The LPF process is uses for treatment of copper ores in which part or all of the copper occurs in oxidized form presents a problem for recovery. Sulphidization of the oxidized copper minerals using sodium sulphide or sodium sulphydrate is sometimes effective to render the minerals floatable, but generally sulphidization techniques produce low recoveries. Many […]
How Antimony is Processed by Flotation
The problem discussed in this antimony process study is limited to a concentrator capable of beneficiating 150 tons per day of antimony ore. The antimony in this study occurs as the mineral stibnite (Sb2S3) in association with small amounts of pyrite, arsenopyrite, galena and lead sulfantimonides. The gangue is composed largely of quartz but contains, in […]
Effect of Cyanide on Depression of Sulphide Minerals
At the dosage of collector (not shown but relatively low), it is indicating galena will not float above pH 10.4, and it is not affected by NaCN. What you have to be careful about is that these lines all move if you increase or decrease the collector dosage. For example, you can get pyrite to […]
Slurry Distributor
The Slurry Distributor (Self-Rotating or Motorized) is a simple, accurate, positive unit that distributes Slurry automatically wherever material must be distributed to several machines or circuits for treatment. The self-rotating distributor is powered by the force of the material being distributed. No operator or adjustments are necessary. Self-Rotating Pulp Distributor The Slurry-Pulp Distributor is […]
Types and Models of Sample Cutters & Samplers
AUTOMATIC SAMPLERS A compact unit designed to move the sample cutter through the stream at a uniform speed up to 30″ per second to provide an accurate increment sample. Action of cutter and mechanism closely adheres to theoretical “perfect technique” in cutting a sample. High speed cutter travel often eliminates need for secondary sampling. Sample […]

Electromagnetic Separation
Starting with a mixture of any of the above minerals it may be determined whether or not they can be separated by high tension, magnetic, or gravity methods and whether any one, or a combination of “Electromagnetic Separation” methods is required. If the minerals appear in different columns they may be separated by high tension and/or […]
Uranium Ore Processing Methods
The process flowsheet of Uranium generally outlines the latest proven processes for uranium concentration known as “Resin In Pulp” more commonly referred to as RIP To date it is not applicable to ores containing vanadium, where the vanadium must be recovered. Crushing Uranium Ore Depending upon ore shipment schedules, it is desirable to operate the […]
