Galena – Sphalerite Flotation & Separation Method
The problem of treating oxidized lead-zinc ores for the production of high-grade lead zinc flotation concentrates is a complex problem due to the nature of the ores and to the soft sliming characteristics of the lead and zinc minerals. The ore for treatment is a lead-zinc carbonate ore in a mixed siliceous-lime carbonate gangue. The association of […]
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 […]
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 […]
Small Gold Processing Plant
The problem a Small Gold Processing Plant can solve is for the need to to provide a small, relatively simple and inexpensive gold mill that will operate at a reasonable profit with a minimum of supervision. The limited availability of skilled operating personnel, availability of water and local power, high cost of transporting ore and expense […]
Sulphide Gold Ore Treatment by Leaching and Flotation Process
Problem with gold recovery from sulphide ore: How may a mill get the maximum recovery of gold from a sulphide ore, at the least capital cost and at the same time obtain the highest net return. This latter point is most important. In many cases a gold mill using an all-cyanide flowsheet with fine grinding of […]
Flash Flotation with Closed Circuit Grinding
The reason why you need Flash Flotation in a Closed Grinding Circuit relates to “Recovering your mineral as soon as free” which has long been recognized in ore dressing practice. This not only applies to gravity treatment but also to flotation. For this application the Flash Flotation Cell was developed for use in the grinding circuit and […]
Easy Mill Expension: Grind Less, Float Coarse, at Higher Tonnage
The Problem with Coarse Flotation and Recovery Many flotation plants today are grinding to fine sizes. This means that money is being spent grinding worthless gangue which might be discarded at a coarser mesh. Many plants are treating ores in which the gangue is free at a coarse mesh and where a coarse bulk concentrate […]
Chalcopyrite (Cu) Sphalerite (Zn) Separation by Flotation
The Problem with separating Copper from Zinc by flotation The treatment of heavy sulphide ores of copper containing zinc and pyrite is often extremely difficult particularly if soluble copper and sulphates are present. This is usually the case in ore deposits near the surface or in tropical countries where the annual rainfall is quite high. The […]
