The Old Copper Smelting Plants

“Karabashmed” is without doubt one of the oldest copper smelting vegetation of the South Ural situated within the metropolis of Karabash. The primary exercise of the plant is making blister copper from copper focus with a preliminary enrichment of copper-zinc ores and in addition from recycled copper uncooked materials.

One other firm we gonna go to is “Kyshtymskiy Electrolytic Copper Plant” which is within the metropolis of Kyshtym of the Chelyabinsk area. It makes copper cathodes, copper rods and valuable metals from blister copper and copper-containing secondary uncooked supplies.

“Karabashmed”, JSC. is a metropolis forming firm of Karabash.

Right this moment it’s the one metallurgic firm in Russia wotking with an superior expertise “Ausmelt”. In November 2006 one “Ausmelt” copper-smelting furnace changed six 100 years previous shaft furnaces.

Right here previous shaft furnaces was once positioned.

Copper focus loading.

The primary constructing of the processing plant and inside is a ball mill with a central loading of copper-zinc ores.

The brand new furnace allowed to extend the plant efficiency as much as 90 thousand tons of blister copper a 12 months whereas fume gasoline quantity decreased sixfold.

The overall view of the “Ausmelt” furnace.

Matte loading.

The content material of the melting furnace flows into the settler the place it releases gasoline. The admixtures stand up as slag whereas the heavier copper blister sinks to the underside.

The alloy temperature is 1150 C.

The slag comes out from the mixer furnace.

It’s fairly a spectacle!

The gear of the corporate had not been modernized in any respect within the Soviet instances and by the top of the 20th century the ecological state of affairs grew to become very severe in Karabash.

In June, twenty fifth, 1996 Karabash and neighbouring territories had been characterised because the zone of ecological catastrophe.

For the reason that starting of the XXI century the corporate’s manufacturing has been slowly modernized and extra eco-friendly applied sciences have been put into operation.

In 2009 Karabash was excluded from the listing of the cities with the best degree of air air pollution.

“Kyshtymskiy Electrolytic Copper Plant” makes copper and valuable metals (as a byproduct of copper refining).

Hearth refining.

The method is happening within the copper smelting store.

The store is provided with a tilting furnace “MAERZ” with capability of 380 tons and a pouring complicated M-24.

Taking samples from the smelting furnace “МAERZ” for figuring out the chemical composition and the extent of metallic readiness.

Anode filling machine “Outokumpu”.

Additionally they have a reverberatory furnace An-1 with capability of 140 tons and efficiency of 42 thousand anodes a 12 months.

Electrolysis baths.

The machine separating anodes for 102 mm.

Separation of copper electrolysis. They’ll obtain very excessive purity of copper cathode (common copper content material in cathodes – 99.997%).

Loaded matrixes with cathode copper.

Then they wash residues from anodes.

This conveyor packages cathodes.

They produce valuable metals from blister copper and copper-containing secondary uncooked supplies. That is how gold initially seems to be like.

Virtually prepared gold bullions.

Copper rod making course of.

It’s made by steady casting and rolling.

Steel is provided to the casting wheel. Adjustment earlier than coming into the rolling mill.

Copper rod packaging.

Test samples.

The plant yearly makes about 100 tons of copper rod, greater than 100 thousand tons of copper cathodes, greater than 100 tons of silver and three,7 tons of gold.
