Lead Refining Dross- - Metalcess

The furnace can be designed with effective working volume minimal 0.15m3, suitable for the recovery of anode slime, PM-containing smelting slag, lead refining dross and all kinds of dust. It can also treat secondary material like scrap copper, WEEE/PCB/IC and etc.

Removing Dross

Dross is the impurity found in precious metals that must be removed so the metal can be used to create a thing of beauty. It is important to understand that the metal already has significant value before the dross is removed, but it's removal reveals the true value of the precious metal, which can then be molded into something of beauty and purpose.

Rotary Reverberatory Furnace (Anode Furnace)-Pyrometallurgy-

Rotary reverberatory furnace, also named as anode furnace, is especially used to treat copper scrap (Cu 92% and above) to get copper anode (Cu 99%), which can be further purified by electrorefining to produce 99.99% Cu cathode. The copper cathode can be processed by upward casting machine to standard copper rod.

Aluminum Dross Furnace Salt Slags Processing

The salt slag generated ranges up to 35 pct of the melt charge in rotary furnaces. Higher quality scrap is melted in reverberatory furnaces, using a flux consisting of equal parts sodium chloride and potassium chloride with 2 to 5 pct cryolite. Dross from this type of furnace ranges up to 10 pct of the melt charge.

process of removing the dross or slag from the molten metal

Put the crucible in a furnace Heat to 1,100 degrees Celsius Dross will rise to the surface Periodically remove the crucible from the furnace and skim the impurities off the surface of the molten gold Stir the gold after each removal of dross and before returning it to the furnace Repeat this process until dross stops rising to the surface

Furnace Operations to Reduce Dross Generation

While it is generally acknowledged that dross generation should be kept to a minimum, too often, the importance of maximising the aluminium content of the dross is overlooked. Some mistakenly believe that a low metal content is a good thing and that the aluminium is being kept in the furnace. In reality, this metal is most likely being lost due to insufficient cooling and thermiting.


date back to 2006, when low salt 10 ton capacity rotary furnace had been used for a year in the company Confal Inc. We contacted the former researchers from the research center in Bridlicna and Dobris where they did the research work on the properties of aluminum dross taken from the salt rotary furnaces and on aluminum dross in general.

Lead smelting - Wikipedia

The lead containing components are processed in blast furnaces for hard lead or rotary reverberatory furnaces for fine particles. The blast furnace is similar in structure to a cupola furnace used in iron foundries. The furnace is charged with slag, scrap iron, limestone, coke, oxides, dross, and reverberatory slag.
