Additionally, he was the author of the paper. As easily-accessed sulfide mineral deposits are depleted, producers must mine the more complex sulfides, which are more difficult to process. The concentrates from these sulfides contain various impurities, like arsenic, in copper minerals such as enargite and tennantite. These minerals are present in many copper orebodies. La enargita es un mineral del grupo de los sulfuros, y dentro de estos al subgrupo de la estannita. Químicamente es un sulfuro de arsénico y cobre. Presenta como aspecto típico un hábito masivo negro, aunque también puede adoptar la forma de cristales alargados rayados. Fue descrita por primera vez en 1850 en Perú. .
