Mineral processing is a technique to separate the valuable minerals from waste rock by treating crude ores and mineral products. The major operations carried out in processing are sampling, analysis and dewatering. Final product obtained from mineral processing can be of high grade taken directly into metal extraction, such as iron ore into iron and steel. In some cases it becomes necessary to concentrate the ore into intermediate product and subjected to extractive processes to recover the purified metal.
High-impact journals are those considered to be highly influential in their respective fields. The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
