Pre-Treatment Processes

• Raw Material

  For our Copper Recovery & Refining division – majority of our raw materials come from electrical waste and electronic equipment which contain electrically powered components. In general term this is called “e-waste”. e-waste is a source of precious metals, such as gold, palladium, platinum and silver, and base metals, such as copper.

EXTRACT COPPER AND PRECIOUS METALS

Smelting

Shan Poornam’s Copper Smelting furnace is specially designed to extract copper and precious metals from electronic scrap and e-waste. Our smelting technology is run on a form of renewable energy known as waste-to-energy. The e-waste charged into the furnace contains carbonaceous materials such as plastic which is burned off to release energy that is used in smelting. This process is a form of energy recovery, it is also a clean and renewable energy source. Our technology is designed to promote efficiency of smelting by using an injection lance to feed material at an even flow in a distributed manner inside the furnace. Doing so ensures uniform reaction and even heat distribution that results in the optimized performance of the furnace. Additionally, all output from the furnace are recycled to be used back into consumers raw material, promoting circular economy.

Output

The output of the furnace is known as black copper which goes for further refining to extract pure copper and precious metal content.

Byproduct

The byproduct of this process is slag which is used as an aggregate in the construction industry.

TSL FURNACE

SWARNA/Copper Plant

Swarna is a state of art Top Submerged Lance furnace using Scada, closing the material cycle enabling energy recovery. Copper blister produced will undergo copper refining in Copper Tank House where copper cathodes of purity 99.99% are produced. Slime deposited at the bottom of the tank will undergo a hydro metallurgy process in our specially designed high tech recovery equipment with an auto dosing system to optimally recover the precious metal. Recovered precious metal will further be refined using our customized equipment with a specially designed condenser equipped with reactor to optimize the yield and produce high purity of precious metals such as gold, platinum, palladium and silver. Refined precious metals with purity up to 99.99% are then sent to PGM Casting Department and cast into the respective ingot using a dedicated furnace.

Recovery & Refining

FIRE REFINING AND ANODE CASTING

In Shan Poornam, we use our Anode Furnace to further refine black copper through oxidation and reduction processes. The product from the Anode Furnace is called an Anode Copper and it is casted by a semi automatic casting machine. Anode copper contains a high percentage of copper along with precious metal content and it goes into our in-house Copper Electro Refining division for further recovery.

COPPER ELECTRO-REFINING

Modern copper refining technology is employed at SPM to extract a pure copper cathode of purity 99.98 % from our copper anode. The byproduct of this process is a slime with precious metal content that is recovered at our in house PGM refining facility.
