About this document
Chalcopyrite Transformation in Roasting Process by Nina Variedades is a document available to read on EtoBox.
This paper examines the transformation of chalcopyrite, a copper sulfide mineral, during the roasting process of copper concentrate in a fluidized bed reactor. Roasting is an important step in traditional copper extraction that involves partially oxidizing the chalcopyrite. The researchers analyzed samples using various techniques to observe how the chalcopyrite grain structure changes with oxidation time, forming layers of oxides and copper sulfides like bornite. Their results supported existing theoretica
