Atomic Model of Gold Adsorption onto the Pyrite Surface with
Mar 21, 2022Adsorption mineralization of gold is an important mineralization mechanism under epigenetic and low temperature conditions. In this paper, a plane-wave pseudopotential method based on density functional theory (DFT) is used to explore the adsorption mechanism of gold on the surface of pyrite. Among the three surfaces of pyrite, the surface energies of (100), (111),

Arsonopyrite Should Be Used To Extract Arsenic Poisoning
There are many deadly minerals that litter the Earth's crust, and without proper research and warning innocent victims might fall to lethal toxins from these minerals. One of these minerals, Arsenopyrite, is a vastly spread and highly dangerous arsenic ore, touching Arsenopyrite without protective equipment can cause arsenic poisoning.
