    Process. Bioleaching can involve numerous ferrous iron and sulfur oxidizing bacteria, including Acidithiobacillus ferrooxidans (formerly known as Thiobacillus ferrooxidans) and Acidithiobacillus thiooxidans (formerly known as Thiobacillus thiooxidans).As a general principle, Fe 3+ ions are used to oxidize the ore. This step is entirely independent of microbes.

  • Alkaline leaching of lead and zinc by sodium hydroxide

    According to Table 2, it can be concluded that leaching process of lead and zinc from low-grade oxide ore using sodium hydroxide is controlled by diffusion process. Consequently, the equations representing the kinetics of leaching process of lead and zinc can be expressed as according to Eqs.,, respectively.

    The cyanide process is as explained below-The ore is grounded and crushed. If the ore containing the gold has other forms of metals or any kind of sulphide minerals then it requires additional kind of treatments before going through the process of leaching. The gold is mixed with the sodium cyanide which leads to the following Elsener’s equation and reaction. This is done to make soluble

  • Extraction Of Silver Mineral Processing & Metallurgy

    The extraction of silver by the solving processes simple. The ore is first roasted with salt in the usual way, whereby the formation of base metal chlorides cannot be avoided entirely. After roasting, the ore is first subjected to leaching with water, in order to extract the base metal chlorides, and then with hyposulphite of lime, to extract the silver.

    The 3 most common commercial biomining processes are: 1. Slope Leaching. Fine ore is kept in a large, slope-shaped dump. During slope leaching, a water solution made of inoculum is continuously sprayed over the ore. After that, the leach liquor (or remaining liquid) is gathered at the bottom and processed for supplemental metal recovery. 2. Heap Leaching. In this technique, the ore is arranged
