Industry grade zinc sulphate heptahydrate originally come from natural zinc ore. There are many types of zinc ore, as zinc blende, smithsonite, zincite and willemite troostite, etc.
Chinese zinc ore general contains lead, which is also called as lead-zinc deposit. Lead-zinc deposit spread all over the country. Followed as the mining facilities development and lead-zinc deposit distribution there five bases has been formed in Northeast, Hunan, Guangdong & Guangxi, Sichuan & Yunnan and Northwest, which accounts for 95% of the country's total zinc output.
1, Hunan lead-zinc base: Hunan is abundant in lead and zinc mineral resources, which is the country's largest base of lead and zinc.
2, the bases in Guangdong and Guangxi provinces;
3, zinc lead base in northwest, mainly distributes in Gansu Shaanxi and Qingdao provinces.
4, lead and zinc base in Yunnan and Sichuan. Yunnan lead-zinc mineral resources are very rich too, and now its lead and zinc reserves occupies the first position in China.
5, Northeast lead and zinc base, is one of earliest bases in our country.
The zinc sulphate heptahydrate manufacturers located to the zinc ore has great advantages on the logistics cost, producing technology and product quality.
