Spent pot liner recycling - Salt slag recycling / salt

Spent pot lining is an extremely hazardous waste and has long been a problem waste stream for primary aluminium smelters.. Due to its hazards, landfill of SPL is banned in many countries. SPL contains toxic compounds including leachable fluorides and cyanides, plus it reacts with water; hydrolysing to produce explosive gas mixtures of hydrogen and methane.

Saltcake | The Aluminum Association

Saltcake is the slag generated during the recovery of aluminum in Rotary Furnaces. To maximize metal recovery, a salt flux is often added to aluminum scrap and dross in the recovery process, and the residue resulting from that aluminum recovery process is referred to as saltcake or saltslag.

Black dross,what is black dross? - Brightstar

At temperatures above the melting point of the salt flux mixture, the black dross consists of two immiscible liquid phases: aluminum metal and liquid salt containing oxide particles and films. As the oxide content increases in the salt flux, the mixture becomes less fluid and more viscous in nature.

Hazardous aluminum dross characterization and recycling

In the United States of America, dross production was approximately 800,000 tons in 1998 with an incremental rate of 3–4% per year (Adeosun et al., 2014; Shinzato and Hypolito, 2005). When salt cake is also taken into account, total accumulation of both wastes is almost 900,000 tons per annum in the United States (ALUMITECH, 2000).

Recycling industrial minerals: not so "secondary"

RVA essentially processes the salt slag generated from secondary aluminium processing from aluminium scrap, yielding a "secondary" alumina which can be used in non-metallurgical alumina markets. Approximately one tonne of secondary aluminium produced yields 550kg salt slag, which can yield 300kg of secondary alumina.

Aluminium Recycling and Environmental Issues of Salt Slag

Abstract Environmental friendly recycling is the trend toward total recycling of aluminium metal. In the secondary aluminium industry, due to the complexity of compositions and contaminants in the various types of aluminium scraps, an understanding of the behavior of different scraps during melting is crucial in the recycling process. Salt slags are the byproducts of the secondary aluminium

Management and valorization of aluminum saline slags

The best systems were those in which salt is not included in the recycling of aluminum as this presents a disadvantage in terms of electricity costs. Removal of the aluminum and storage of the remaining slag in landfill or secure deposits is the cheapest option, especially if the aluminum content exceeds 5 wt.%.
