Under these conditions, the highest recovery of lead and zinc was obtained to be and %, respectively. In the second stage, the dissolution kinetics of lead and zinc was evaluated by the shrinking core models. The finding reveals that diffusion through the fluid film was the leaching kinetics rate controlling step of lead and zinc.

Extraction purification lead zinc titanium chromium mineral ores raw ... How do extract zinc from oxide, sulfide or carbonate ores? ... that has a low density and a high resistance to corrosion which makes a good structural material.
Use a bone ash cupel.. base metals oxidize and actually dissolve in the cupel. this works on lead especially, leaving a ball of precious metals to be seperated..
Of the more than 60 minerals that contain lead, only 3 galena, cerussite and anglesite are commercially viable. Usually, lead is found in conjunction with other metals such as silver and zinc. Lead materials are mined as a by product of these other more valuable metals. Extracting the lead materials from the ore is a multistep process.
Zinc recovery from Dross. adv. A discussion started in 2006 but continuing through 2018. 2006. Q.

Silver processing, preparation of the ore for use in various products. Silver has long been valued for its white metallic lustre, its ability to be readily worked, and its resistance to the corrosive effects of moisture and oxygen. The lustre of the pure metal is due to its electron configuration,
The proposed process is intended to extract zinc and lead from EAFD without destroying the iron oxides matrix. So, this material can be recycled by the steel industry.
As a result, almost of lead and a significant proportion of zinc were volatilized from the real molten fly ash samples at 1173 K. In contrast, for the model fly ash, volatilization ratios of lead and zinc at 1173 K were only 85% and 25%, respectively.
