What is Aluminium Dross?
Aluminium Dross is byproduct that is created on the surface of molten aluminium or alloys of aluminium when it reacts with oxidation in the smelting and recycling process. It is a non-homogeneous semi solid mixture of recoverable metallic aluminium in an aluminium oxide and salt mix and usually contains 15-80% recoverable metal.
Types of Aluminium Dross
Being as prominent aluminium dross manufacturers in Maharashtra, we provided different types which are given below.
Primary dross types
- White dross: Produced in the initial smelting of bauxite or in the primary melting of scrap-aluminium. Has metallic aluminium content that is high (15-75%), and therefore can be recovered. Reduced content of salt flux.
- Black dross: Formed during the recycling of secondary or on the further processing of white dross. Has less metallic aluminium, and more concentrations of aluminium oxide and salt fluxes. Is able to have 5 percent to 30 percent of aluminium and hence not very efficient to recycle.
Other classifications
- Salt cake dross: This dross is also referred to as salt slag and contains a significant amount of salt. It is produced following recycled dross or scrap of aluminium.
- Flux dross: It is formed in the fluxing process that is utilized to eliminate impurities and is highly concentrated with flux materials.
- Skimming dross: Aluminium dross dealers Maharashtra is a layer that develops on the top of a melted aluminium.
- Sweating dross: This is produced when the molten aluminium cools.

Benefits/Features of Aluminium Dross
We as aluminium dross dealers in Maharashtra, according to different environment we provided benefits which are given below.
- Recovery of Valuable Metals: A significant proportion of the mass of dross is metallic aluminium which can be successfully melted down and recovered. This conserves a lot of energy and expenses as compared to extraction of primary aluminium using the bauxite ore.
- Environmental Sustainability: Recycling dross will significantly lower the amount of hazardous waste to the landfills. This is in line with the current sustainability aspirations and reduces the impact of the production of aluminium on the environment.
- Source of Aluminium Oxide: The non-metallic product that can be left behind after the extraction of the metal is also an invaluable mineral, which is primarily aluminium oxide. This remains can be used to aluminium dross manufacturers in Maharashtra other industrial products resulting in a zero-waste process.
- Cost-Effective Feed Material: In the case of secondary smelters, Aluminium Dross Recycling Unit is more economical to purchase and process such dross containing high content of metal as compared to purchasing pure aluminium scrap.
Key Characteristics of Aluminium Dross
We as prominent aluminium dross buyers in Maharashtra, different key characteristics are there which are given below.
- Variable Metallic Content: The percentage of real metal of aluminium in the dross may vary considerably, as low as 5 per cent and more than 80 per cent. The value of the dross, as well as the particular recycling method will be determined by this content.
- Very Reactive to Moisture: Hot dross is very aggressive to moisture, and could produce heat, poisonous vapor, and inflammable gases such as hydrogen. This also requires special and regulated cooling and handling and delivery to be safe and retain metal value.
- Fluxing Agents Present: Aluminium dross manufacturers in Maharashtra,may contain salt fluxes (chlorides and fluorides) to be used during the melting process, especially in Black Dross. The level of salt has to be controlled in the recycling process because it is a challenge to the environment when it is not treated or neutralized.
- Forms (White vs. Black): White Dross is a primary production by-product, which has a high content of metallic aluminium, and a low content of salt; Black Dross is a secondary refining by-product with a high content of salt/oxide.
Applications of Aluminium Dross
We serve as prominent aluminium dross manufacturers in Maharashtra, it is applicable in different site which are given below.
- Secondary Aluminium Production: Aluminium Dross Powder is mainly used in melting the rich part of the metal to extract aluminium ingots to cast and alloy.
- Refractory Materials: The non-metallic portion (rich in aluminium oxide) is treated and utilized to make heat resistant lining to furnaces.
- Fluxing Agents: There are certain grades of dross powder used as a synthetic flux in steelmaking and in other foundry work in aluminium dross granules.
- Ceramics and Abrasives: The hard alum oxide material is employed in the production of several ceramic products and in the manufacture of industrial abrasives in Aluminium Dross and Scrap Recycling Furnace.
- Cement and Concrete Additives: Treated dross residue may be added as cement and concrete blends to increase strength and decrease the use of virgin material in aluminium dross buyers in Maharashtra.
