Gold is the most malleable and ductile metal with higher melting point and stable chemical property. In the past, gold is used as currency and decorations. Now, in addition to additional roles, gold has become an important industrial raw material with the progress of the society and the development of production. For example, spun gold is used as the conductors of integrated circuits in computers.

Silver is an argenteous metal with good ductility and the best thermal and electric conductivity among all kinds of metals.
Therefore, silver is often used to produce the physical equipment components of high sensitivity as well as a range of automated devices, rockets, submarines, computers, nuclear installations and communication systems. A great number of contact points in all of this equipment are made with silver. In addition, a variety of silver compounds are indispensible and important elements in civilian and industrial production.

The Shaanxi Fengxian Sifang Gold Mine Co., Ltd. and the Shaanxi Silver Mine are both the subsidiaries of Shaanxi Non-ferous Metal Holding Group Ltd, and respectively engaged in the development of gold and silver resources with an annual production of 1t refined gold and of 50t silver concentrates. In order to be a resource-saving enterprise, over the years, both firms have been persisted in strengthening details management to enhance economic operation level, and underlining technological study to solve the issues in mining and dressing, while initiating technical transformation to increase extraction ratio to provide sufficient power for the enterprise¡¯s sustainable development.
