Nickel minerals can be divided into three major groups, including nickel sulfides, nickel arsenides and nickel antimonides, normally the minerals of magmatic and hydrothermal origin, nickel silicates and other similar compounds. From the sulfide minerals, the most abundant are pentlandite, rloanlit and nickelin.

14.11.2022In recent years, the average copper ore grade has drastically decreased, falling from 0.9% (2019) to 0.7% (2021). The reason behind the decline of mineral ores is the rapid aging of mineral resources. Since more chemicals are needed to recover the desired mineral, the requirement for mining flotation chemicals rises as ore grades
