Discovery Walks On Primary Deposits Of Diamond

Diamond deposits of China may be classified into magmatic-type (i.e

. kimberlite-type), primary diamond deposits and placer diamond deposits. The retained reserves of the former make up over 95% of the total, while those of the latter only nearly 5%. According to the morphologies of orebodies, i.e. diamond-bearing kimberlite bodies, primary diamond deposits may be divided into the pipe type, dike type and sill type. More than 20 kimberlite pipes have been found in China, mainly distributed in Shandong and Liaoning. The section of the pipes is generally round, elliptical and irregular in shape and a few to a few hundred meters in diameter with a ratio of long diameter to short diameter of about 21 to 41. They show a pinch-and-swell structure in section and become dikes to a certain depth. The pipes generally dip very steeply at dip angles of 75to 85. They have a high diamond potential. Most primary diamond deposits in China belong to this type.Henan Hongxing Mining Machinery Co., Ltd is the professional manufacturer of complete sets of mining machinery, for example,ball mills,hammer crusher Welcome all of you to visit our official website.sand washing equipment:http://www.hx-crushers.com/p42.html Over 400 kimberlite dikes have been discovered in China, occurring in Liaoning, Shandong and Guizhou. Part of them contain diamond, but few of them are of industrial value. Up to now it is known that only the Hongqi Nos. 1 and 5 kimberlite dike primary diamond deposits at Mengyin, Shandong, have industrial value.Kimberlite sills are present in Shandong and Henan. They are intruded gently (generally at a dip angle of 10) along the bedding of the country rocks. The sills have a low ore potential and seldom form industrial deposits. According to the formation ages, diamond deposits may be divided into ancient placer deposits and modern (Quaternary) placer deposits. Placer diamond deposits of industrial va-lue in China are all modern (Quaternary) placer deposits, distributed in Shandong, Hunan, Liaoning and Jiangsu. They include eluvial, hillside, deluvial and elluvial placer deposits.Henan Hongxing Mining Machinery Co., Ltd is a joint-stock mining machinery manufacturing enterprise integrated in scientific research, production and marketing. It is located at the High & New Technology Industries Development Zone of Zhengzhou,China with an area of 50 thousand m2 which includes 15,000 m2 of standard heavy duty industrial workshop. Equipments are more than 160 pieces, including large and medium sized metal processing, riveting and installing equipments. There are more than 660 workers including 80 administrators with secondary and senior occupational titles and engineering technicians. In order to promote the competitive strength, the advanced technologies have been introduced from America, Germany, Japan and Australia, which established the international advanced production line, first-class modern testing base as well as research centers of sand maker, mill and mine-selecting equipment. Scientific management, advanced processing technology and innovative manufacturing theory make the company become the mining machinery manufacturing and exporting base in China.
