However, other fractions, in particular those generated by the nonferrous metal mining industry, may contain large quantities of dangerous substances, such as heavy metals. Through the extraction and subsequent mineral processing, metals and metal compounds tend to become chemically more available, which can result in the generation of acid or alkaline drainage.

Nickel in a circular economy. The concept of a circular economy is generally understood to be quot;a regenerative system in which resource input and waste, emission, and energy leakage are minimised by slowing, closing, and narrowing energy and material can be achieved through long lasting design, maintenance, repair, reuse, remanufacturing, refurbishing, and recycling 1.
