Here, iron mineral supplemented thermophilic composting (imTC) is proposed and demonstrated for enhancing OH production and accelerating the maturation of composting. The results indicated that the maximum OH production of imTC was 1922.74 μmol·kg -1, which increased by 1.39 times than that of ordinary thermophilic composting (oTC).

Mineral refining is the process of separating and purifying raw minerals. The refining process typically begins with the mining or extraction of ores and minerals and ends with a final product of pure metals and minerals. Mineral refining can also involve other complex processes such as smelting, stripping, and roasting.
1. Introduction1.1. History of Process Mineralogy. Historically, the design of concentrators treating sulphide ores was treated with the tools available at the time – for example, pioneer work by Bond (1952) for work index and mill sizing, and the various empirical sampling and testing of drill core and other geological samples or specimens, …

Mineral Processing. Mineral processing is the process in which chemical or physical methods are used to separate the useful minerals in the ore from the useless minerals (usually called gangue) or hazardous minerals, or to separate multiple useful minerals. In the early years, mineral processing was called mineral concentration or …

Without mineral resources, industry would collapse and living standards would plummet. In 2010, the average person in the U.S. consumed more than 16,000 pounds of mineral resources 1 (see Table 5.6.1 5.6. 1 ). With an average life expectancy of 78 years, that translates to about1.3 million pounds of mineral resources over such a person's ...
