This causes most of the zinc ore to sink to the bottom and the lead ore to float to the top. The lead ore then gets skimmed off. (Additional chemicals, such as copper sulfate, allow the zinc ores to be skimmed off later in the process.) At this stage, the lead particles skimmed contain between 40 to 80% lead.

Don't forget to use the Super Duper perk card when you melt your Lead Ore later on. Farming Lead Ore is an efficient way to get Lead in Fo76. Use one of the following two ways to farm Lead Ore:
Prior to mining, all rocks contained in a mineral deposit must be placed in one of several categories known as ore types. Each ore type describes a different way that the rock will behave in processing. The ore type determines which process stream a particular mined unit will be sent to, sets expectations for process engineers and …
The history of lead and zinc mining in Arkansas is linked because ores of these two metals often occur together. Lead and zinc in Arkansas occur principally along the upper White River and its tributaries in Baxter, Boone, Independence, Lawrence, Marion, Newton, Searcy, Sharp, and Stone counties. Other locations include the Kellogg …
The mining techniques for lead typically depend on the deposit type. Open-pit mining is often used for large surface deposits, while underground mining is applied to deeper …
Copper is a metal that is widely used in different applications mainly due to its thermal and electrical conductivities, together with its corrosion resistance, particularly when it is alloyed. This chapter intends to be a summary of the copper metallurgy: from the historical aspects and mineral deposits or statistics to the different technologies used to …
Lead (Pb) is next in abundance with 120 to 150 lead-bearings minerals known. The commonest lead ore is the sulphide galena (PbS). Other forms are known but don't often occur as ore minerals. An important lead mineral worth mentioning is vanadinite (Pb5(VO4)3Cl). This lead mineral is sought, not for its lead but for the strategic metal, …
