The mixed ore contains oxide, supergene oxide, and hypogene sulphide copper species, with the greater part of the deposit being made up of sulphide and mixed ores. The oxide ore has a much higher copper grade In porphyry copper deposits, the copper ore often is composed of two main parts including oxide and sulfide ores. The oxide rock type consists a fraction of total Co-simulating Total and Soluble Copper Grades in an Oxide Ore Deposit

Experimental and statistical modelling on copper recovery
ABSTRACT This study aims to investigate the recovery of copper from a low-grade source of an ore deposit in sulphuric acid solution. In this study, a full-factorial statistical design model and Artificial Neural Networks (ANN) are applied to develop an analytical approach to understand the dissolution parameters better. Temperature, time, There are two distinct types of copper deposits: sulfide ore and oxide ore. Currently, the most common source of copper ore is the sulfide ore mineral chalcopyrite, which accounts for about 50Types of Copper Deposits in the World (Updated

Assessment of water quality effects on flotation of copper–cobalt oxide ore
As could be seen from Fig. 1, Fig. 2, when the ore was floated with NCK process water, the initial recoveries of copper and cobalt decreased below 25% and 30%. Copper and cobalt grades have dropped as well. However the final recoveries for both copper and cobalt have exceeded 70%. It is reported that feed water quality variation has Peter Russell The oxidized zone of ore deposits has fascinated me for many years because of the process of their formation and the resulting reddish brown rocks. The colourful rocks are a signal to prospectors that economic ore cannot be far away.

Cloncurry METAL Petrophysics Toolkit online Academia.edu
The Cloncurry district is renowned for Iron-Oxide Copper-Gold (IOCG) mineralization, but includes a wide spectrum of deposit styles, including: IOCG, Iron Sulfide Copper-Gold, Broken Hill Type (BHT), Sedex, Skarn and intrusion related Cu-Mo. Measurements were made of: density, magnetic susceptibility and Natural Remanent Magnetization (NRM), Copper slags are a by-product generated from copper extraction. Rich in iron oxide, silica, calcium oxide, and alumina, copper slags are mostly stockpiled or used in landfill applications. These slags consist of a substantial amount of valuable metals in an entrained metallic, sulphide or dissolved oxidized form, copper being one of them.Comparison of single and mixed reagent systems for flotation of copper

Ni/Co–Cu Sulphide Ores, Key Contributors to Sustainability
2.1 Mineralogy of Nickel-Copper Sulphide Ores. Studies on the geology and mineralogy of domestic nickel-copper sulphide ore deposits are reported in several sources in detail [16,17,18,19]. Although over 20 minerals have been identified in these complex sulphide ores having primarily nickel, copper, and iron metals in a variety ofThe treatment of copper sulfide minerals containing a high percentage of oxide copper causes problems in the concentration process, decreasing the copper content. In order to increase the efficiency of the concentration process, it is necessary to treat the copper oxide component by leaching the grinded ore prior to the flotation, or byA Review of the Cyanidation Treatment of Copper-Gold Ores
