Gold telluride in sheet metal concentrate can be decomposed after long-term cyanidation in alkaline cyanide solution, but pre-calcined
Au 2 Te+O 2 
2Au+TeO 2
The gold is reduced to a metallic state and is more easily decomposed.
Further, when telluride symbiotic pyrite sulfides, etc., by firing at the same time to remove them.
Tungsten alloys rods are made from a mixture of tungsten and other metals such as nickel, copper, and iron. These alloys have high density, high melting point, and excellent mechanical properties, making them ideal for use in various applications.
Tungsten alloys rods are commonly used in the aerospace industry, as they have excellent radiation shielding properties and can withstand high temperatures. They are also used in the medical industry for radiation therapy and in the automotive industry for balancing weights.
The composition of tungsten alloys rods can vary depending on the specific application. For example, a high-density tungsten alloy rod may contain 90-97% tungsten, while a radiation shielding tungsten alloy rod may contain 90-95% tungsten, 3-5% nickel, and 1-2% copper.
Tungsten alloys rods are a versatile and reliable material that can be used in a wide range of industries and applications.
