At current gold prices this is worth about US$600. Both smelter treatment charges and oxidation or bio-leach costs are at least $200/t of concentrate and payables/recovery in the 90% range, so a minimum GSR for effective downstream processing is around 0.5. Clearly this is a function of gold price, but in the current gold price and cost ...

Equipped with tough milling tools and power supplies, they can create jewelry like rings, bracelets, pendants and earrings from a block of a material. Some of them are capable of working with precious metals like gold and silver – but to do so a machine needs to rotate tools with at least 30000-60000 rpm since those metals are soft.
