Bioleaching is the simple and effective technology for metal extraction from low grade ores by the use of microorganism. The role of bacteria in bioleaching was found in 1947. • In 1950 copper dump leaching was found. First industrial gold bioleaching plant in 1980. • There are two processes of Bioleaching: • Direct bioleaching and Indirect bioleaching. • In direct bioleaching minerals which are susceptible to oxidation undergoes direct enzymatic attack by the microorganism. • In indirect method of bioleaching of minerals bacteria produce strong oxidizing agent which reacts with metals and extract them from the ores. • #biotechnology #environmentalscience #industrialsolutions #industialbiotechnology • YouTube channel link: / @shabirahmad1234
