For the study, a magnetite ore was received from LKAB Luossavaara Kiirunavaara Aktiebolag, mine in Malmberget, Sweden. The sample contained magnetite of high purity 5457 Fe 3O 4 Figure 1, with quartz, ilmenite, actinolite, albite, biotite, apatite, and diopside as gangue minerals with
mineral inputs of a conventional car, and an onshore wind plant requires nine times more mineral resources than a gas-fired power plant. Since 2010, the average amount of minerals needed for a new unit of power generation capacity has increased by 50 as the share of renewables has risen. The types of mineral resources used vary by technology.
A growing demand for products made of jewelry and ornamental stones, including nephrite, requires an increase in mining volume. However, only less than 30 of the extracted raw material is suitable for processing. The rest of the low grade nephrites are substandard and unclaimed, and they negatively affect various life spheres. In this regard, their involvement in industrial turnover is an ...
