Cermets or composite materials are composed of ceramic and metal materials. The metal acts as a binder to protect the brittleness of the ceramic which provide resistance. Tungsten carbide (WC) is the most commonly used cermet in a wide range of indus

Currently, processes are being developed to recover precious metals from refractory minerals, such as tellurides (e.g. AuTe2, Ag3AuTe2) and selenides (e.g. Ag2S). When Te and Se are found in the leaching solution, they interfere with subsequent proce
