硫酸化焙烧

石煤提钒低温硫酸化焙烧矿物分解工艺

Mineral decomposition process of vanadium recovery from stone coal by low temperature sulphating roasting

该工艺可使焙烧的阳极泥量减少，有利于提高转窑生产能力，同时减少硫酸化焙烧时硫酸用量，从而减少SO2的排放。

This novel process could also reduce the amount of anode slime needed to be roasted , and the production capacity of rotary kiln would be enhanced greatly .

金精矿硫酸化焙烧酸浸液萃取铜试验研究

A Study on Copper Extraction from Acid Leaching Solution of Sulfatizing Roasted Gold Concentrates

贵金属富集工艺中大量铜的分离方法包括硫酸化焙烧法、氧化焙烧法、硝酸溶解法、稀硫酸选择氧化溶解法、控制电位氯化法等。

The main methods of the macro-copper separation in the precious metals concentration technology is sulfuric acid roasting , oxidation roasting , nitric acid resolution , diluent sulfuric acid oxidation resolution selectivity , and control potential chlorination .

在铜阳极泥的处理过程中，无论是硫酸化焙烧、高压浸出、全湿法浸出还是选冶联合处理都要产生富含金、铂、钯的硒、碲富料。

In the treatment process of copper anode slime , the material , which is rich in gold , platinum , palladium , selenium and tellurium would be produced as the method of sulfated roasting , high pressure leaching , aqueous leaching , or combined with dressing-metallurgy .
