Explanation:
Statement 1:
Biomining is not the scientific process of excavation, treatment, segregation, and gainful utilization of aged municipal solid waste lying in dumpsites. The correct definition of biomining is the process of using microorganisms to extract metals from ores and mine waste. Therefore, statement 1 is incorrect.
Statement 2:
Bio oxidation, Bioleaching, Dump leaching, and Agitated Leaching are indeed various methods of Biomining. These methods involve the use of microorganisms to extract valuable metals from ores or waste materials. Bioleaching, for example, is a process where bacteria break down minerals to extract metals. Therefore, statement 2 is correct.
Therefore, the correct answer is option C, as the second statement is correct while the first statement is incorrect.

Consider the following statements :1. Biomining is the scientific proc...
According to the Central Pollution Control Board (CPCB) guidelines, "Biomining is the scientific process of excavation, treatment, segregation and gainful utilisation of aged municipal solid waste lying in dumpsites typically referred to as legacy waste." Simply put, it is a process of treating garbage or waste with bio- organisms or natural elements like air and sunlight. Over time, the biodegradable component of the waste gets decomposed through the natural process, and the remaining part i.e., the non-biodegradable material, is then dealt with separately. It extracts metals of economic interest from rock ores or mine waste. Biomining is a method of extracting minerals and metals from their parent ores using naturally occurring biological processes. The practice requires none of the environmentally damaging processes found in conventional refinement methods and instead relies entirely on the natural interaction of biological organisms. So, Statement 1 is correct.
Biomining comprises 4 steps: excavation of legacy waste, stabilizing the waste using bioremediation, segregation of excavated waste, and sustainable management and its safe disposal. The methods of biomining include Bioleaching, Bio-oxidation, Dump leaching, and agitated leaching. Bioleaching is a process in mining and biohydrometallurgy (natural processes of interactions between microbes and minerals) that extracts valuable metals from low-grade ore with the help of microorganisms. Bio-oxidation is a natural biological treatment process (green process) used for the biological control of air pollution. Combusting any fuel generates oxides of nitrogen (NOx), particulate matter, sulphur dioxide (SO2), and carbon monoxide (CO). Heap leaching: freshly mined material is moved directly into heaps that are then bioleached. Dump leaching: low-value ore or waste rock is placed in a sealed pit and then bioleached to remove more of the valuable metals from the waste pile. Agitated Leaching: crushed rocks are placed into a large vat that is shaken to distribute the microbes and material evenly and speed up the bioleaching process.
So, Statement 2 is correct.
