Mineral Beneficiation | Hazen Research

Mineral beneficiation is the process of concentration, and was first described in Agricola's famous treatise, De Re Metallica, published in 1556. The earliest ores to be discovered and processed were of such high grade that they did not require beneficiation, and they satisfied mankind's needs for nearly 3,000 years.
