This document complies with the provisions of GB/T 1:1-2020 "Standardization Work Guidelines Part 1: Structure and Drafting Rules of Standardization Documents"
Drafting:
This document replaces GB 29145-2012 "Energy consumption limit per unit product of roasted molybdenum concentrate" and GB 29146-2012 "Unit product of molybdenum concentrate"
Energy Consumption Limit" and GB 31340-2014 "Energy Consumption Limit of Tungsten Concentrate Unit Product": With GB 29145-2012, GB 29146-
Compared with GB 31340-2014 in:2012, in addition to structural adjustments and editorial changes, the main technical changes are as follows:
a) Changed the quota requirements and indicators for tungsten concentrate, molybdenum concentrate and roasted molybdenum concentrate (see Chapter 4, Section 4 of GB 29145-2012
Chapter 4 of GB 29146-2012 and Chapter 4 of GB 31340-2014);
b) Increased energy consumption requirements per unit product of molybdenum concentrate of SABC production type (see 4:2);
c) The production type of energy consumption per unit product for roasting molybdenum concentrate has been changed to multi-hearth furnace and internally heated rotary kiln (see 4:3, GB 29145-
Chapter 4 of:2012);
d) Added the calculation method of comparable energy consumption per unit product of tungsten concentrate and molybdenum concentrate (see 6:2);
e) The raw ore grade conversion coefficient has been changed (see Appendix C, Appendix C of GB 29146-2012 and Appendix C of GB 31340-2014):
