antimony is a silver-white brittle solid or a dark-gray, lustrous powder. It can be harmful to the eyes and skin. antimony can also cause problems with the lungs, heart, and stomach. workers may be harmed from exposure to antimony and its compounds. the level of exposure depends upon the dose, duration, and work being done.iron was first exploited by the hittites in asia minor and it was brought to syria and ere israel by phoenician merchants. another source of iron was tarshish, and massive iron was brought from vedan and javan the early iron age in ere israel corresponds roughly with the period of the philistines (from 1200 In the oxygen-enriched smelting of jamesonite, it was shown from the observation results that the oxidation reaction proceeded by three stages. during the initial step of smelting, the oxidation products were lead-antimony alloy and iron-enriched gudmundite. then the selective oxidation of sulphides of lead and antimony continued.
