Abstract:

According to EPA, 21% of global greenhouse gas emission is from industry sector and mining sector is one of the major emitters of greenhouse gases. Scientists are certain that climate change effects are expected to increase in the coming decades and urge nations to implement mitigation measures. Implementation of green technology at industrial level reduces global warming, greenhouse effect, pollution and climate change. Present study aims to explore the importance of green mining of garnet and garnet based abrasive water jet cutting in reducing greenhouse gas emission and climate change effects. M/s V.V. Mineral implemented two common sense steps manual mining and solar drying to address the challenge of climate change in mining and beneficiation of garnet. The case study finding shows manual mining operation adopted by M/s V.V. Mineral for garnet sand mining is green and completely reduced the emission of 0.893-1.19 kg CO2/ton sand, normally emitted through mechanized mining process practiced in the area. Implementation of solar drying in the beneficiation process results in elimination of 29.67-32.36 Kg CO2 emission by every ton of sand dried in fossil fuel based driers. Garnet is the commonly used abrasive around the world. Garnet based abrasive water jet cutting is an environment friendly green process. Since it is a cold process, all materials can cut without fuel combustion and heat generation process. This paper highlights the advantages of replacing thermal cutting process by garnet based abrasive water jet cutting in mineral fabrication sector to reduce air pollution in the form of fumes and gases and reduces CO2 emission and global warming.
