What Is A Bioreactor And How Does It Work?

2020/09/04A bioreactor provides an ideal environment where cells can focus on what they are supposed to do: proliferate. Like lab workers, cells can only produce consistently good work if the conditions are right: it should not be too hot or too cold, and they have to have enough nutritous food and fresh air. In terms of a bioreactor, this means maintaining pH, temperature, ensuring sufficient gas

2016/03/253. The need for Biomining and Bioleaching Biomining will become more important as high- grade surface mineral deposits are worked out and become less viable, and mining companies will be forced to find other mineral sources. These will include the working of low-grade ore deposits, mine tailings, mine dumps, and worked-out mines.

6 Types of Phytoremediation

2019/12/03The Concept of Phytoremediation. Phytoremediation is a cost-effective, plant-based approach to remediation that takes advantage of the ability of plants to concentrate elements and compounds from the environment and metabolize various molecules in their tissues. It refers to the natural ability of certain plants called hyperaccumulators to

Biomining

Biomining is the technique of extracting metals from ores and other solid materials typically using prokaryotes, fungi or plants (phytoextraction also known as phytomining or biomining).[1] These organisms secrete different organic compounds that chelate metals from the environment and bring it back to the cell where they are typically used to

2020/05/06Background Bioleaching has been attracting attention in the recent years as an emerging sediment heavy metal pollution remediation technology. However, the use of sulfur powder as sulfur substrate causes the problem of "post-acidification", and the free bioleaching functional bacteria which are susceptible to environmental impact during reactor operation cannot be used efficiently for

Bioleaching

Bioleaching. Bioleaching—a biomining process—uses direct metabolism or byproducts of microbial processes to solubilize a metal sulfidic ore or waste into an aqueous solution, and it is used at commercial scale for the extraction of base metals, for example, copper, tin, or zinc [11, 19].

Bioleaching: metal solubilization by microorganisms

1997/07/01Bioleaching 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.
