Heat treating leadantimonyarsenic alloys is a highly useful tool for bullet casters A BHN range can be selected for any given loadfirearm combination we are loading for and BHN variation will be kept to an absolute minimum the trick is to not over do it
The most common and important metal alloyed with lead is antimony Antimonial lead alloys usually contain from 1 to 6 percent antimony but they may contain as much as 25 percent Other components usually include tin iron copper zinc silver arsenic or traces
The relative bioavailability of arsenic antimony cadmium and lead for the ingestion pathway was measured in 16 soils contaminated by either smelting or mining activities using a juvenile swine model The soils contained 18 to 25 000 mg kg–1 As 18 to 60 000 mg kg–1 Sb 20 to 184 mg kg–1 Cd and 1460 to 40 214 mg kg–1 Pb The bioavailability in the soils was measured in kidney liver
Arsenic antimony and germanium have presented strong enhancement in signal strength under argon atmosphere while lead has shown no sensitivity to ambient gas type Detection limits of 11 mg L −1 10 mg L −1 13 mg L −1 and 02 mg L −1 were obtained for As Sb Pb and Ge respectively
The successful cyanidation of gold ores containing appreciable amounts of arsenic or antimony sulphide minerals such as orpiment realgar and stibnite is usually difficult or even impossible Extractions are low and the solutions soon become ‘foul’ The gold in such ores could be free and uncoated and no trouble in dissolving it in clean cyanide solutions would be expected

Arsenic cadmium chromium cobalt lead mercury and nickel are elements that are present naturally in the earth They are among a group of substances commonly referred to as heavy metals
1 Introduction Arsenic and antimony share some chemical and toxicological properties 1 2 instance both metalloids act as clastogens but do not have mutagenic properties their trivalent species are responsible for the mediation of their toxicological effects and their biological halflifes are relatively short in mammals although there is evidence that certain parts are retained
