zinc ore grinding method

Zinc smelting Wikipedia

Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals, e.g. iron, because in contrast, zinc has a low boiling point.At temperatures typically used for smelting metals, zinc is a gas that will escape from a furnace with the flue gas and be lost, unless specific

How to Process Lead-Zinc Ore by Gravity and Froth

Dec 16, 2020· Flotation process and equipment of lead-zinc ore In the beneficiation of lead-zinc ore, flotation is an important process. Mixing in mixing tank: After the ground pulp is classified by the classifier, it enters the mixing tank for mixing. Control the slurry concentration at 25-35%, then add flotation agent to control the slurry pH value 9-11 and stir it for 6-15 min.

Treatment Methods of Lead & Zinc Ore

Lead and Zinc Ores Minerals of lead and zinc commonly are rather closely associated in nature; zinc-free lead ores and lead-free zinc ores are exceptional rather than common, although there are such. Lead and zinc ores usually contain some silver, but those of the Mississippi Valley region are silver-free. Indeed, lead-zinc ores often are commercially valuable chiefly because of their silver
