Phytomining is the production of a `crop' of a metal by growing high-biomass plants that accumulate high metal concentrations. Some of these plants are natural hyperaccumulators, and in others the property can be induced.
This ensures that the xenobiotic is safely stored, and does not affect the functioning of the plant. However, preliminary studies have shown that these plants can be toxic to small animals (such as snails), and, hence, plants involved in phytotransformation may need to be maintained in a closed enclosure.

Oct 01, 2019· Bioleaching is the use of bacterial microorganisms to extract precious metals, such as gold, from ore in which it is embedded.As an alternative to smelting or roasting, miners use bioleaching when there are lower concentrations of metal in ore and they need an efficient, environmentally responsible method to extract it. The bacteria feeds on nutrients in minerals, thereby separating the .
"Biosolids" is a term often used in wastewater engineering publications and public relations efforts by local water authorities when they want to put the focus on reuse of sewage sludge, after the sludge has undergone suitable treatment processes.In fact, biosolids are defined as organic wastewater solids that can be reused after stabilization processes such as anaerobic digestion and composting.
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
Titled "Phytoremediation of Metals", the patent disclosed a method to remove metal ions from soil using plants. Several species of plants, including radish and mustard, were genetically engineered to express a protein called metallothionein. The plant protein binds heavy metals and removes them so that plant toxicity does not occur.

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.
Several patents were taken out on nickel phytomining between 1998 and 2004. However, nickel phytomining is still not in operation as a commercially viable activity anywhere in the world. Nickel phytomining makes use of plants that naturally accumulate metals, and there are more than 400 species known to do this.
