US Patent for Process for continuous refining of quartz

1996-3-22  A rotating cylindrical quartz glass tube is partitioned into at least 3 chambers comprising a pre-heating chamber, a reaction chamber, and a gas desorption chamber. The process comprises pre-heating the starting quartz powder by continuously supplying it into the pre-heating chamber, refining the powder by transferring it into the reaction chamber in which the powder is brought into contact

8 Types of Gold Ore- Properties and Ways to Process

2 天前  8 Types of Gold Ore- Properties and Ways to Process. Gold mainly appears in the form of natural gold and minerals in the ore such as pyrite, tellurium ore, sphalerite, and gold in gangue, etc. About 70% to 75% of the gold in the deposit is in the form of natural gold, while the other 20% occurs in the form of telluride. The remaining 5% to 10%

Extraction of Gold

When the gold has solidified, the molten silver chloride collected on the surface is run off, carrying with it a small proportion of gold. When silver is the chief impurity in the gold, as in that found in Australia, the process is specially applicable. The gold has a degree of purity of 99.1 to 99.7 per cent.
