zinc wheel weight casting with? | Trap Shooters Forum

Sep 17, 2010· I bought a set of sinker molds and have a spare crucible for melting lead (zinc). Big one for lead is a 200 pounder, small one for zinc is 50 pounds. As I cull the weights for shot making the truck weights, etc. go to the sinker pot. I agree that the zinc is more brittle than lead but I find that 'truck weights'/stick on weights added to the ...

Zinc and Lead - Arkansas Geological Survey

Zinc (Zn) is a bluish-white lustrous metal that is brittle at room temperature, but malleable when heated. It has a low melting point (419.5°C) and a moderately high specific gravity (7.13). Lead (Pb) is a soft, ductile, malleable, bluish-white metal with a low melting point (327.4°C) and a high specific gravity (11.3). Zinc and lead minerals often occur together because, as elements, they ...

Copper, Lead and Zinc Smelting and Refining

The lead is refined in a cast iron kettle by five stages. Antimony, tin and arsenic are removed first. Then zinc is added and gold and silver are removed in the zinc slag. Next, the lead is refined by vacuum removal (distillation) of zinc. Refining continues with the addition of calcium and magnesium.

Lead smelting - Wikipedia

Plants for the production of lead are generally referred to as lead smelters.Primary lead production begins with sintering.Concentrated lead ore is fed into a sintering machine with iron, silica, limestone fluxes, coke, soda ash, pyrite, zinc, caustics or pollution control particulates. Smelting uses suitable reducing substances that will combine with those oxidizing elements to free the metal.

Fluxing Zinc in the Backyard Foundry – bolis.com

Zinc and slag. According to the backyard foundry experts, the most useful casting metal that's even easier to melt than aluminum is zinc. It melts around 420°C/800°F, so you can even melt it on a hot stove. It casts harder than aluminum for better wear, and zinc/aluminum alloys can approach cast iron in strength and durability. Sounds great!

How do I determine if something is lead? - Instructables

Lead has a low melting point (328 C). You can melt it by heating it in a steel can using a propane torch. You can also melt zinc (420 C) this way, but it is a little more difficult. So you could put both a piece of zinc, and your coin, into a steel can heated by a torch, and then you watch to see which one melts first.
