Leaching of secondary zinc oxides using sulphuric acid
The ore is processed in a sulphuric acid atmospheric leaching circuit, followed by solvent extraction and electrowinning. Zinc casting is used to obtain the 99.995% SHG zinc final product. With Skorpion Zinc's predicted mine closure date of 2017 approaching, the company is investigating various possibilities for maximizing zinc throughput.

LEACHING Zn FROM THE LOW-GRADE ZINC OXIDE ORE IN …
temperature, leaching time, stirring speed and liquid-to-solid ratio on the zinc leaching from low-grade zinc oxide ore in a NH3-H3C6H5O7-H2O system were studied. The results showed that the zinc leaching rate is only 4.7% when the citric acid concentration is 0 M, and the leaching efficiency of Zn increased with increasing ...

Corrosion of Zinc‐Containing Cabal Glasses by Various ...
Zinc oxide replacing calcium oxide in cabal glasses of constant 40 mol% B 2 O 3, 30 mol% Al 2 O 3, caused a decrease in chemical durability in all leaching solutions used. The corrosion was found to be linear with time in the limit of investigation (1–4 h) but with different rates depending on the type of leaching solution or temperature.

The effect of particle size on the leaching of metal from the zinc concentrate was studied. In these experiments, the initial alkaline concentration 5 mol/L, leaching temperature (358 K), L/S 10:1 and leaching for 2 h were maintained as shown in Fig. 2.The results of Fig. 2 showed that Zn leaching recovery kept at the level between 79% and 77% when ores size was more than 76 µm.

Zinc smelting - Wikipedia
Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals, e.g. iron, because in contrast, zinc has a low boiling point.At temperatures typically used for smelting metals, zinc is a gas that will escape from a furnace with the flue gas and be lost, unless specific ...
