Foreword
Instead of the standard YS/T 300-1994 "germanium enrichment."
Compared with this standard YS/T 300-1994, the main changes are as follows.
--- The standard name changed to "germanium concentrate";
--- The original standard a special, two special merger premium increase JGe-8 level so that the lower limit extends to concentrate germanium content of 1.0%;
--- Increasing the limit hydrochloric acid insoluble germanium and fluorine content;
--- Germanium concentrate according to sources of raw materials are divided into two categories. one is the production of germanium from coal concentrate, three grades; the other is made of other materials (such as
Lead, zinc, copper, iron smelting, etc.) production of germanium concentrate, a total of nine grades;
--- Analysis sampling sample from the "bag (barrel) sample taken the same amount of" to "remove the bag and its quality is directly proportional to the amount of";
--- Original standard Appendix A ~ Appendix E "germanium concentrate chemical analysis" as a separate national standards for reporting, and adds a fluorine-containing
Determination of the amount.

Germanium concentrate
1 Scope
This standard specifies the germanium concentrate requirements, test methods, inspection rules and signs, packaging, transportation, storage and contents of a contract.
This standard applies to the extraction of germanium from lead-zinc, coal, iron ore, copper and other raw materials of germanium concentrate, as production of crude germanium tetrachloride, carbon
Germanium, metal germanium raw materials.
