(1) Gold ore main type is auriferous quartz vein type.

(2) The geochemical characteristics of REE in the auriferous quartz veins indicate that the ore forming f.

(3) The gold metallogeny is characterized by auriferous pyrite and occurred in the alternating layer of heavy-layer metasandstone, flaggy metasandstone and graphitization schist.

(4) The occurrence and distribution auriferous quartz is strictly controlled by NNE - NE fault.

(5) It is indicated that placer gold and antimonial (auriferous) quartz-calcite vein, calcite vein are the same origin, which are major of the metallic matter resources.

(6) An experimental research on auriferous high - sulfur copper ore flotation with a new reagent was carried out.

(7) In the northwest of China, auriferous altered cataclasite, adular- sericite quartz vein and quartz reef types are present(), and metallogenetic epoch is mainly Hercynian period.

(8) The micromorphology of quartz crystals formed at different ore-forming stages in auriferous quartz veins are studied by means of differential interference microscope.

(9) NE - NW - and nearly EW - trending fissures induced from the major fracture are infilled with auriferous quartz.

(10) Through modification of operating condition, there are three classes of pure auriferous pyrite headmill.
