![]() Consequently optimum conditions can be obtained with high levels content of temperature, acid concentration, and time with low levels of phenol and pulp density. Including temperature, acid concentration, and time were selected as more effective parameters. The free element, produced by reductive smelting, is a hard, lustrous, silver metal. As with nickel, cobalt is found in the Earth's crust only in a chemically combined form, save for small deposits found in alloys of natural meteoric iron. Therefore, it was concluded that phenol was one of the factors in effective the leaching process. Tools Cobalt is a chemical element with the symbol Co and atomic number 27. Although the effect of phenol content on cobalt leaching was too low but dissolution of cobalt decreased in the absence of phenol. ![]() The effecst of time and acid concentration on SN ratio were also determined at about 8% and 4 %, respectively. The results indicated that temperature was more effective on SN ratio (Signal to Noise ratio) which was found to be about 80%. Copper typically occurs as chrysocolla (CuOSiO 2. Cobalt (pronounced /koblt/) is a hard, lustrous, grey metal, a chemical element with symbol Co. These factors included temperature, acid concentration, time, phenol content, pulp density, and interaction between some of the parameters. The main cobalt-bearing mineral in the copper-cobalt oxide ore deposits of the DRC is heterogenite (CoO.2Co 2 O 3. In this paper, cobalt ore was leached with sulphuric acid in the presence of phenol to determine the effects of various factors on leaching.

Reductive leaching was used to dissolve metals, especially cobalt, present in Fars Tidar mine. Abstract This presentation outlines key aspects of cobalt properties, production and applications. Cobalt produces brilliant blue pigments which have been used since ancient times to color paint and glass.
