HG/T2674—1995
Phosphate Rock for Yellow Phosphorus
Published on April 2, 1995
Ministry of Chemical Industry of the People's Republic of China
Implemented on January 1, 1996
WHG/T2674—1995
This standard has revised ZB/TD51002—86 "Phosphate Rock for Yellow Phosphorus". The principles of this revision are to give full consideration to the use requirements, closely combine with the actual situation, reasonably use national resources, promote technological achievements, improve economic benefits, achieve advanced technology, reasonable economy, convenient use, and coordinate with relevant standards. In this revision, the classification of the previous version is adjusted according to GB/T12707-91 "Guidelines for the Classification of Industrial Product Quality", divided into three levels, and some control items are adjusted, SiO2 is replaced by SiO2/CaO, and Fe2O: items are cancelled, so as to be more in line with production practice; necessary adjustments are made to various technical indicators according to process requirements, combined with domestic resource conditions, production status and opinions of all parties, and with reference to international commodity mine conditions; the compilation rules are carried out in accordance with GB/T1.1-1993. This standard replaces the original professional standard ZB/TD51002-86 of the People's Republic of China from the date of implementation. This standard is proposed by the Technical Supervision Department of the Ministry of Chemical Industry of the People's Republic of China. This standard is under the jurisdiction of the Chemical Mining Design Institute of the Ministry of Chemical Industry. The responsible drafting unit of this standard: Chemical Mining Design Institute of the Ministry of Chemical Industry. Participating drafting units of this standard: Jinhe Phosphate Mine, Kaiyang Phosphate Mine Mining Bureau, Yunnan Phosphorus Chemical Industry (Group) Company, Jingxiang Phosphorus Chemical Industry Company, Yichang Phosphorus Chemical Group Company, Xinyang Phosphate Fertilizer Plant, etc. The main drafters of this standard are Wang Hailiang, Zhao Zhiquan and Wang Heping. This standard was first issued in August 1986.
This standard is entrusted to the Chemical Industry Mining Design and Research Institute of the Ministry of Chemical Industry for interpretation. I
