Mining is the extraction of valuable minerals or geological materials. Mining is done using two excavation types: Surface mining and sub-surface mining. After excavation, the mineral is processed using techniques like Extractive metallurgy and Mineral processing. There are many environmental issues like erosion, loss of biodiversity and ground water contamination by chemicals from mining processes. Many companies are now enforced to follow good environmental standards.
Scholarly peer review is the process of subjecting an author's scholarly work, research, or ideas to the scrutiny of others who are experts in the same field, before a paper describing this work is published in a journal. The work may be accepted, considered acceptable with revisions, or rejected. Peer review requires a community of experts in a given (narrowly defined) field, who are qualified and able to perform reasonably impartial review.
