Recycling of Niobium Slag by Disintegrator Milling
Abstract
<jats:p>The main aim of the study is recycling of niobium slag, separating valuable metallic Nb and mineral ballast – calcium aluminate. Niobium slag is a waste product from Nb production at NPM Silmet OÜ. For the retreatment of slag, an efficient disintegrator milling technology was used. Laboratory grindability tests of slags were carried out. We propose a potential principal scheme of slag treatment, consisting of preliminary size reduction by impact milling at direct mode and final at separative mode using a disintegrator milling system DSL-115. As a result of slag pretreatment, pure Nb from a coarse fraction was separated. To elaborate an industrial technology, semi-industrial tests for specifying recycling modes and finding optimal milling parameters were performed. Granulometry studies of milled products and chemical composition as of Nb as well as that of remained products were conducted. Yield of Nb with purity 90–95% was in the range of 0.4–1.0%. Preliminary cement tests for using the main product as a binder or a substitute of cement confirmed its potential for use in building materials production.</jats:p>
