How are even advanced nations still discovering such vast sums of mineral deposits? I was under assumption that the creme de la creme has already been exploited.
China industrialized much later. Much of the country especially the interior has poorly known geology.
Also more advanced technology makes it economically viable to recover deposits that previously would not have been viable to recover.

CGN Proton Therapy System


on November 6 that the first commercial multi-room proton therapy equipment production base in China, invested and built by CGN Nuclear Technology Development Co., Ltd., welcomed the first equipment to roll off the production line today, and is officially ready to be shipped to Chengdu Medical Investment West China International Cancer Treatment Center Hospital for installation and commissioning .

base was completed last year. it has been intensively carrying out the production, assembly, testing, final assembly and integration of domestically produced commercial proton therapy systems. With the launch of the 230MeV (mega-electron-volt) cyclotron, the independent production and integration of core components of the proton therapy system has been successfully achieved .

It is reported that after fully acquiring the world's leading multi-chamber proton therapy technology, CGN Technology spent four years on research and development and achieved the first independent production of proton therapy accelerators .

CNNC Technology said that CNNC's proton therapy equipment is equipped with the first domestically produced 360° rotating gantry , which has the world's largest irradiation field of 30 cm * 40 cm and the world's smallest beam spot size. It can flexibly adjust the angle to irradiate the patient's tumor site without moving the treatment bed, reducing the connection of irradiation fields. The number of patients treated in a single treatment room can reach up to 500 per year .
