Diamond Processing Flow Chart of Beneficiation
This is a Diamond Processing Chart as it was done in the 1950s. World demand and production of diamond both for gem and industrial purposes has increased nearly five-fold during the past 25 years. Improved mining and recovery methods together with the discovery and development of new fields has enabled mining operations to fill the […]
Crushing & Screening Plant Design Factors
Crushing Plant Design and Layout ConsiderationsCrushing Circuit “A’’ shows a small simple layout for use in mills up to 100 tons. In order to keep the flowsheet simple, and because of the use of the forced feed type of crusher, we can crush small tonnages up to 100 tons per day with a very simple […]
Agitated Copper Leaching & Cementation Process
Copper Agitated Leaching and cementation process of copper problem: The treatment of copper ores, both oxides and sulfides by means of flotation, hydrometallurgy or other processes has been well established for many years. Flotation has been applied generally to the treatment of sulfide ores, both in small and large scale operations. Hydrometallurgical methods alone or in combination with flotation have […]
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 […]
Mineral Processing and Extractive Metallurgy Methods
A successful search for and development of a new mineral deposit rests not only in its discovery but also in economical processing of the ore. Via the Science of its engineering, Mineral Processing and Extractive Metallurgy allows the evaluation of metal recovery Methods laid-out or expressed as a process flowsheet. The challenge of discovery and development, […]
Copper and Pyrite Separation by Selective Flotation
The Problem with copper-pyrite ores This flowsheet, is designed for the treatment of a copper-iron sulfide ore containing appreciable values in gold. The major portion of the gold is associated with the copper but the pyrite contains appreciable gold values also. The demand for pyrite for sulphuric acid also gives added incentive for the recovery […]
Copper Sulfide Flotation
Copper Sulfide Flotation Circuit Beneficiation of Copper Sulfide by Flotation Copper, due to the present world demand and price, is of foremost interest to the mining industry. Many new properties are either in the process of being brought into production or are being given consideration. Copper minerals usually occur in low grade deposits and require […]
Designing a Conveyor System
The Problem with Designing a Conveyor System The designer of belt conveyors is often faced with problems of determining the proper belt speeds, belt widths, number of plies in the belt, and idler spacing for conveyors employed in various parts of a mill. Equipment Company offers the following data and tables, based upon many years of […]
Coal Beneficiation Process Diagram
The Problem with Coarse and Fine Coal Beneficiation Economic and operating conditions make it important to provide a simple, low cost, efficient method for recovering fine coal from washery waste. Not only is the water pollution problem a serious one, but refuse storage and disposal in many areas is becoming limited and more difficult. Many breakers […]
Chromite Beneficiation Process
The Problem with Chromite Processing Experience indicates that chrome ores are concentrated to best advantage by gravity methods. Since recoveries are generally very poor in the fine sizes, the gravity flowsheet must be designed to remove the chrome as soon as liberated by crushing and grinding. For example, if the chrome is not entirely freed […]
