2015年3月1日 · Fortunately, I found some locations that were claimed and registered as antimony/gold mines sometime in the early 20th century. I've already scouted the locations and recovered some samples that I believe are antimony oxides as well as gold bearing oxides in quartz. This area is unusual in that it is a placer antimony deposit.

2015年5月20日 · Hello guys. I wish to ask that, is there any geological or geochemical connection between antimony and gold? Simply it's a good idea looking for gold on antimony mine areas? I don't know antimony's density but, i remember that i …

The Hillgrove Gold-Antimony project has both open-pit and underground reserves. high grove resources Costerfield Australia's only antimony producer, located in Victoria. In 2019, Costerfield produced antimony as a by-product of gold.

I have found some real nice gold rings that are made for small children and I have noticed very young children at some of the swimming areas with gold bracelets, earring and rings so obviously people do buy good jewelry for kids.

2016年5月26日 · I have a specimen similar to the ones you have pictured on the right hand side, I found mine as a child and took it to many in the field geology and none could identify it, and comparing it to galena or antimony... well galena has the right color but not the right texture or weight, the antimony is similar but antimony isn't porous and it's still too bright in …

2024年4月7日 · The difference is caused by the Minie-bullet being made of 100%-pure lead. Burnside bullets were made of "a hardened-lead alloy." In this case, "hardened" meant the manufacturer increased the hardness of the lead by adding another metal (such as Zinc or Antimony") into the molten lead during the casting process.

2019年5月8日 · The reason is, pure lead is actually a soft metal, and firing lots of soft lead bullets through the gunbarrel caused a buildup of "lead smearing" inside the gunbarrel's rifling grooves. So, "hardened-lead" alloy (for example, lead mixed with Antimony or Zinc) was developed to eliminate the gunbarrel-clogging produced by using soft pure-lead ...
