Jun 02, 2016 Mineral Processing and Ore Dressing. Before the event of ore dressing, crude ores were shipped directly to the smelters, or the refineries, with the shipper paying the freight and treatment charges. These charges varied with the type of ore and the distance from the smelter. In all cases they were many times our modem milling costs. Mineral processing or mineral beneficiation or upgradation involves handling of three primary types of ROM ore material which has been blasted, fragmented and brought out from in situ position. These materials can be used directly or by simple or complex processing and even applying extractive metallurgy like hydrometallurgical or pyrometallurgical methods.

rocks). The Table-1 enlists the possible ore minerals and gangue minerals in the ores from wide range of deposits. From mineral processing point of view, it is important to identify the ore and gangue minerals (mineralogical study), their textural relationship Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy. The primary operations are comminution and concentration, but there are other important operations in a modern mineral processing

Abstract. The principal gold minerals that affect the processing of gold ores are native gold, electrum, Au-Ag tellurides, aurostibite, maldonite, and auricupride. In addition, submicroscopic (solid solution) gold, principally in arsenopyrite and pyrite, is also important. The main causes of refractory gold ores are submicroscopic gold, the Au-Ag tellurides, and very fine-grained gold ( 10 m) locked in sulfides. Based on the mineralogical characteristics and mineral processing techniques required, gold ores can be classified into 11 types (Table 1). Some metallurgical implications to these gold ore types are summarised below Placers, quartz vein gold ores and oxidized ores Generally, placers, quartz vein gold ores and oxidized ores are free-milling and gold can be recovered by gravity and/or direct cyanide

Expert systems have proved to be ideal candidates especially for the control of mineral processes. An expert system based on on-line classification of the ore type has been developed. Self-organizing maps (SOM) are used for pattern recognition of the type of feed. The course is designed to explain what the users of iron ore are looking for in both physical and chemical properties and how processing the ore can create the necessary properties. Participants will look at the typical types of iron ore deposits and how each may be processed to achieve a sellable product.
