The most commonly used and one of the most accurate methods for refining gold is the fire assay method. This is an industrystandard procedure that, while reliable, is very involved and requires many steps. The process is worth the time and effort it takes, however, because it has been proven to be 20 times more accurate than any other method ...
Gold Refining and Value Addition Minataur gold refinery The Minataur™ refining technology is a unique all hydrometallurgical route, based on solvent extraction, for refining gold to a purity of "five nines" ( per cent). Compared with conventional smelting and electro refining technology, the Minataur process offers:

REFINING eHANDBOOK: Review These Refinery Best Practices 3 P etroleum refining is a highly energyintensive process using both purchased energy (gas and electricity) and byproduct streams from the refining processes. Energy use accounts for approximately 50% of refining costs. As major energy suppliers, refineries must report
petroleum refining industry (SIC 2911, NAICS 32411). In response to this large number of fatal or catastrophic incidents, OSHA initiated CPL, the Petroleum Refinery Process Safety Management National Emphasis Program (NEP), in June The purpose of the NEP was to verify refinery employers'' compliance with PSM.

THE DANGERS OF AQUA REGIA: When adding aqua regia to ore, there can be use a red gas given off; THIS RED GAS CAN KILL Sometimes the ore will bubble over, so watch it carefully. Use the aqua regia in an open area and it to the ore very slowly. Aqua regia cannot be boiled or simmered in the house or where it is not well ventilated. This can cause serious illness or KILL YOU! Use a vent hood with ...
confidence that the longterm interests of the refinery are being served. Ours is not a new facility, having been commissioned near Los Angeles in 1969. Valero''s Wilmington Refinery can process 80,000 barrels of highsulfur heavy crude oil per day; with the purchase of gas oil, the refinery output maxes out at 135,000 barrels per day.
