粗锌是锌制品回收到工厂然后通过一定的工艺进行再次提炼重熔的锌锭，锌含量要看原来的锌制品是什么，提炼的技术和提取能力而定。
适合于粗锌冶炼，以及其它需要进行高低温分段操作的金属冶炼中。
The utility model is fit for the crude zinc smelting and other metal smelting which requires the high-low temperature staged operation.
以电炉粗锌为原料，采用精馏-蒸发-冷凝法生产高品质超细活性锌粉。
High quality super fine zinc dusts are produced with electric furnace crude zinc pig as raw material by using distillation condensation technology.
回收锌废料：锌合金回收、锌渣回收、粗锌回收、破碎锌回收、回炉锌料回收等。
Recycling zinc waste: zinc alloy recovery, zinc slag melt, coarse zinc recovery, crushing zinc recovery, down zinc material recycling, etc.
