Flotation Cell Impeller Types
Receded Disk Impellers Impellers for the “Sub-A” Flotation Machine are built in two types with corresponding wearing plates: Receded Disk Impellers and Diffuser Wearing Plates Conical Disk Impellers and Wearing Plates. The receded disk impellers and diffuser wearing plates have been proved in commercial installations for many years and are one of the important developments made […]
Flotation Machine
The flotation process is widely used for treating metallic and non-metallic ores and in addition, it is receiving an ever widening application in other industries. A greater tonnage of ore is treated by flotation than by any other single process. Practically all the metallic minerals are being recovered by the flotation process and the range […]
Silver Lead Zinc Ore Processing Method using Flotation
Sulphide ore of lead and zinc containing considerable silver was submitted for testing with the purpose of determining a flowsheet for the production of separate lead and zinc concentrates for marketing at their respective smelters. It is necessary to recover as much silver as possible in the lead concentrate as a higher return for this […]
Lead Barite Fluorspar Separation Method
The concentration of fluorspar ores by flotation is well established but the treatment of lead-barite-fluorspar ores has long been recognized as a difficult process generally resulting in unacceptable concentrates with relatively poor recoveries. Intensive research on this problem is continually being conducted to develop favorable reagent combinations and conditions suitable for treating such ores. The […]
Lead Carbonate Beneficiation by Gravity and Flotation
Treatment of oxidized lead ores (Cerussite) has long been recognized as a difficult process often resulting in low grade concentrates and low recoveries. Surface oxidation on galena ores has resulted in high tailings losses. The difficulty in treating oxidized lead ores by gravity methods is due to the softness of the oxidized lead minerals. During […]
Hematite Processing by Flotation
Direct shipping of high grade iron ore, because of depletion or partial depletion of reserves, or high costs of operation has forced operators to use some means of beneficiation to produce an acceptable product with the lower grade iron ore reserves. Deposits of comparatively lower grade iron ore that remain relatively untouched or by-passed, are […]
Single & Double Stage Grinding Circuits
The comparison between single stage and double stage grinding has received much attention in the past few years. In order to submit information for use of mill operators, we have prepared comparative flowsheets for 50 Ton, 100 Ton, 200 Ton, 350 Ton and 550 Ton/24 hour plants, showing both single and two-stage grinding in typical […]
Graphite Beneficiation Process
Graphite is an important industrial mineral. Two types occur in nature, crystalline and amorphus. Crystalline graphite is used principally for crucibles and shaped structures. Amorphus graphite is used extensively in the steel and lubrication industries. In many deposits the two types grade into each other and the ore is of such low grade that beneficiation […]
Gold Washing and Gravity Circuit for Placer Gold
The handling of large quantities of gold-bearing gravels is of utmost importance for most successful placer operations. In addition to providing efficient washing and recovery methods, the placer plant should be constructed as a compact unit that can be readily moved. This is an important consideration because the washing and recovery plant should be close […]
Batch Cyanidation of Flotation Concentrate
The production of gold bullion from gravity or flotation concentrates is often an important economic consideration for an isolated gold mining operation. It is assumed in this case that the coarse free gold has been recovered by the Mineral Jig in the grinding circuit and that the jig concentrate has been amalgamated. This treatment produces […]
