Purification And Smelting System

It is specially designed for processing the gold-silver alloy slime from desorption electrolytic system, Merrill-crow processing system or lower grade gold or silver alloy.

It can separate the gold and silver, improve the gold and silver purity and smelt them into gold ore silver more.

Work together with desorption electrolytic system, Merrill-crow processing system from the Heap leaching, CIL or CIP leaching, vat leaching project or flotation concentrates smelting project.

Features and advantages

(1)Lower investment compares with the traditional system which needs a lot of civil work construction.
(2)Fast delivery by saving a lot of time on the installation.
(3)Easily maintenance and operation.
(4)Modular design and easy adjustment according to the customer’s requirements.
(5)Complete set in the container makes transport much easier.
(6)One-stop refinery system to help you get high purity gold silver.

(1)Gold slime purification smelting processing The gold silver alloy slime will react with the nitric acid in the reactor kiln. Most of the metal such as silver, Iron, Zin, Cu apart from gold will dissolve in nitric acid. The residue is gold slime which will be collected by an corrosion resistant filter after washing. The gold slime from the filter will be sent to the pyrometallurgy smelting oven to be smelted into gold ingot with purity 99% above.

(2)Silver slime purfication smelting process The solution from nitric acid washing will react with hydrochloric acid. The Silver will be collected as Silver chloride residue. Then the Silver chloride willl react with the nitric acid again and the silver will replacement by the Iron powder. The silver slime after purfication will be collected by an corrosion resistant filter after washing. The silver slime from filter will be sent to the smelting oven to casted into silver ingot with purity 99.5% above.

(3)Waste gas processing system The waste gas which generated during the processing will be washed by caustic soda solution before discharged for environment projection purpose.

(4)Gold and Silver casting oven The high purifity gold silver slime after drying will be casted into ingot separately in the pyrometallurgy smelting system container. We do also provide the mould with different pattern base on the customer requirements.
