hi guys after reading this post prompted me to ask this question the picture is of a silver looking substance ive been recovering with trace amounts of gold and black sands ive tried burning it with a butane torch and melting it with no change to its appearence any ideas on what it is ?
It's not mercury if not affected by heat. Smelting is the only way to tell for sure, use the mapp ( methyl acetylene ) gas cannisters , they are yellow. The blue butane/propane torches won't get hot enough.

will do thanks DD
