The recently extracted slag presents a highly alkaline initial pH value of around 13, which is logical if we take into account the fact that this sample corresponds to slag recently obtained in the recycling process of lead and that it contains high levels of sodium carbonate.
The slag is very reactive and can cause fires through 'overheating' especially of large pieces of slag; it is also highly alkaline and therefore corrosive. This paper describes a systematic study of the characteristics of slag samples from a lead acid battery recycling plant, particularly the heat generation and alkalinity.
