Transcript of Bioleaching and Phytomining - Extraction of Copper, Phytoming and Bioleaching Phytomining - How It works This is one way of extracting copper from low grade ores- which are less than 1% copper Advantages of phytomining Bioleaching- Advantages...
Bioleaching is a simple and effective technology for metal extraction from low-grade ores and mineral concentrates. Metal recovery from sulfide minerals is based on the activity of chemolithotrophic bacteria, mainly Thiobacillus ferrooxidans and T. thiooxidans, which convert insoluble metal sulfides into soluble metal sulfates.Non-sulfide ores and minerals can be treated by heterotrophic ...

Phytomining is a new way of extraction of metals of low quality in heavily contaminated metallic conditions. The extraction process is performed by plants, the plants draw up the elements through their roots, it is stored there as the plant grows and then the plant is ...
Bioleaching is the extraction of metals from their ores through the use of living organisms.This is much cleaner than the traditional heap leaching using cyanide. Bioleaching is one of several applications within biohydrometallurgy and several methods are used to recover copper, zinc, lead, arsenic, antimony, nickel, molybdenum, gold, silver, and cobalt

Bioleaching is the extraction of a metal from sulfide ores or concentrates using materials found native to the environment; namely, water, air and microorganisms. In other words, bioleaching is the commercialization of the ability of certain bacteria and archaea, found in nature, to catalyze the oxidation of sulfide minerals.
Oct 15, 2013· Phytomining is the production of a metal crop using high-biomass plants. These crops of high concentrations of desired metals are cultivated, harvested and delivered to .

Bioleaching and Phytomining Extraction of Copper by. Phytoming and Bioleaching Bioleaching- Advantages Disadvantages of phytomining We can use waste ores, reducing the impact of mining on the environment. Phytomining How It works Select plants will absorb copper compounds through their roots, and the compounds become concentrated
Bioleaching: Making Mining Sustainable. The environmental consequences of mining and quarrying are vast, as highlighted in the mining section. Due to an increase in consumerism, heightened dependence on technology, and an overall world population growth, more and more minerals and metals need to be extracted from the earth's surface as shown in Figure 1.
Abstract. Bioleaching is a simple and effective technology for metal extraction from low-grade ores and mineral concentrates. Metal recovery from sulfide minerals is based on the activity of chemolithotrophic bacteria, mainly Thiobacillus ferrooxidans and T. thiooxidans, which convert insoluble metal sulfides into soluble metal sulfates.Non-sulfide ores and minerals can be treated by ...
Recycling helps to conserve energy and resources. ... (phytomining) Plants absorb ... The solution is called a leachate and the process is called bioleaching.
Bioleaching and phytomining are increasingly used to extract copper from low grade ores (see below). The traditional method of extraction is to heat the copper sulfide. Copper(II) sulfide gives copper and sulfur dioxide during thermal decomposition. Thermal decomposition means that the compound breaks down into other substances when it is heated.

Copper is also recycled. Once again this is a more energy efficient process than the extraction from its ore as well the copper ore supply on earth is being depleted at a very fast rate. As a result other methods for the extraction of copper such as phytomining and bioleaching are being used instead. Silver and gold from jewelry are also recycled.
