Much can be gleaned from looking at the dross that is generated in a casthouse; in fact, the quality of dross can provide a good indication of the overall efficiency of the cast house operation. Even with low aluminium prices a reduction in dross generation within the furnace can provide huge savings per year.
In addition to the density data, the particle-size analysis, the distribution of elements in the different fractions, composition, metal content of recovered alloys, and gas evolution were compiled in a dross identity card characterizing each dross and simplifying the preanalysis for recovery.
Dross recycling is different. Aluminium dross recycling is a completely different process to strictly aluminium recycling. Aluminium recycling is where pure aluminium metal products (previously used in another form) are re-melted into aluminium ingots and then re-used to new aluminium products.

Worldwide dross press references for ALTEK now total over 550, it has been proven to be the best technology for recovering aluminium units from dross and is the most widely used dross processing technology in the Aluminium Industry.
1.1 Definition of Dross and General Scope of Related Aluminum Recycling Aluminum Dross is a by-product of Aluminum production. Today much energy is consumed to recover the Al from the dross; energy could be saved if the dross diverted and utilized as an was engineering material. There are two forms of dross –white dross and black dross.
Oct 01, 2009· 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.

aluminium. They are an environmentally friendly alternative to chlorine gas which, although effective, presents major health and safety concerns in its usage and control in a casthouse environment. Two of the most frequently asked questions by users of fused refining fluxes are: • “Which composition of fused refining flux
Hot dross composition. The hot dross composition changes from one plant to another in function of the parameters that control its generation, the most usual composition being: metallic aluminium 60-75% oxide 20-30% salts 5-10% It is evident that the main component of dross is metallic aluminium, and this justifies the action taken by producers
Data Mining Toward Increased Use of Aluminum Dross In a casthouse that produces multiple ﬁnished alloys, it is the composition of dross. These factors include the skim-ming method, composition of the molten alloy, added salt ﬂux composition, and dross-cooling process. The results
Abstract: This research work aimed to apply the aluminium dross, waste of ADC12 and 6063 aluminium smelter grade as the raw materials produced plant fertilizer by acid treatment process with phosphoric and hydrochloric acid. Chemical properties have been tested as a chemical composition, pH, amount of macronutriants and heavy metals.

At regular intervals, the molten aluminium is siphoned from the bottom of the pot into large crucibles and transferred to holding furnaces where alloying of the metal takes place; the liquid metal is sometimes transported to a remote casthouse (see figure). Road transport of molten aluminium between a smelter and a remote casthouse
May 25, 2014· Preserving metal units utilizing the latest generation of aluminium dross press The handling of dross is an unfortunate but necessary activity in any aluminum cast house. One technology designed to cool dross and maximise metal recoveries is the dross press.

Almex USA Inc. is a leading supplier of commercial and aerospace aluminum billet and slab casting technology and equipment.
SMS group designs, supplies, constructs, and commissions machinery and equipment for the aluminum industry worldwide. It focuses particularly on aluminum casthouses, supplying: •Horizontal casting plants for ingots, busbars, and billets •Vertical casting plants for extrusion and forging billets •Open mold ingot casters (air & water cooled)
composition. Finally, after a certain settling time, the casting process starts. To separate large dross particles, a glass cloth channel filter is positioned in front of the SNIF P140 unit. Afterwards, the melt is grain refined and filtered through a ceramic foam filter (CFF) before the melt is distributed to one of the four electromagnetic molds.
On over all material balance, it was found that the ingot shares by 45% of the feed to the casthouse furnaces at Egyptian Copper Work (ECW), net production of the casthouse is 43.76% and the yield of rotary dross furnace (RDF) is 28.8%. The net production of the foil unit represents 35% of the total input to the unit.
They allegedly used at least one latent hydraulic binder or pozzolanic binder or a mixture of them, at least one alkaline activator and aluminum dross in geopolymer composition. Inseemeesak and Rodchanarowan (2013) proposed benefits from aluminum dross as an additive in cement paste. Their goal was to investigate the effect of dross addition on
Growth in the South African use of aluminium in automotive and packaging applications has been impressive in recent years. Before discussing the industry, it is pertinent to briefly discuss aluminium and its alloys. “Aluminium” is a generic term for a group of alloys (wrought and cast) that are characterised by their chemical composition.
