Zinc mixed with lead | Shooters Forum

Antimony hardens lead and is present in many lead alloys. Wheelweights run around 3-4% while Linotype has 11%. The usual method is to add linotype to wheelweight metal and bring the antimony content up to 5-8%. Linotype is hard to find now, and pure Linotype is too brittle for hunting. Tin is also used to harden lead, although it's …

Nano-microbubbles and feed size interaction in lead and zinc …

As in most lead-zinc flotation operations, lead is separated first, followed by the zinc flotation stage. Due to the nature of the ore, lead minerals are frequently released from their gangue in coarse sizes, while zinc minerals need comparatively more grinding to produce the appropriate degree of liberation from accompanying gangue minerals.

Shot Information & Data Tables-ballisticproducts

Lead shot is classified by its antimony alloy content as either chilled or magnum. Antimony is the metal used to harden lead. Antimony is a brittle flaky, crystalline metal with a density of 6.7 grams/cc. Lead, when alloyed with antimony, becomes a harder pellet. As more antimony is added, the overall density of the pellet is slightly reduced.
