Non Ferrous Slag
Characteristics and environmental aspects of slag: a review
Each slag type usually contains a specific suite of elements that may be of environmental concern. In general, non-ferrous slag may have a higher potential to negatively impact the environment compared to ferrous slag, and is thus a less attractive material for reuse, based on trace element chemistry, principally for base metals.

The NFM slag used in this work originates from an industrial non-ferrous blast furnace process, post-treated in a pilot installation using high temperature treatment and quenched via water granulation.
The impact of slag fineness on the reactivity of blended cements with
The heat of hydration of OPC blended with non-ferrous metallurgy slag and the influence of the specific surface area of the slag on the reactivity in these systems was investigated. Heat release of blended cement pastes at early ages revealed decreasing reaction heat with increasing slag content.
CHAPTER 1: Introduction: Metallurgical Slags
Slags are by-products generated by the pyrometallurgical processing of both ferrous and non-ferrous metal ores and secondary resources (recycling). They are …
Slag treatment solutions for non-ferrous metals
The nonferrous metals industry produces large amounts of various slag types. The objective of many producers is to sell the slag as a premium product and avoid dumping costs. Due to tighter legislation, this is becoming more challenging for certain types of slag, because the benchmark for undesired elements and components in the slag is too high.
