Influence of Arsenic on the Chemical Wear of Magnesia-Chromite Refractories in Copper Smelting Furnaces

فصل «Influence of Arsenic on the Chemical Wear of Magnesia-Chromite Refractories in Copper Smelting Furnaces» از کتاب «The Minerals, Metals & Materials Series» بر «ذوب مس» در حوزه «متالورژی مس» تمرکز دارد. محتوا مبانی علمی، روش‌های فنی و پیامدهای عملی موضوع را به‌صورت منسجم توضیح می‌دهد. برای انتخاب فرایند، طراحی واحد، تحلیل بهره‌برداری و رفع عیب در استخراج و پالایش مس مفید است.

Arsenic can be found in different sulfidic copper concentrates and residues, which for several years have commonly been used in copper metallurgy, as the “arsenic-free” resources are getting rare. Due to the high toxicity the removal of arsenic in the copper smelting process is a very important topic. The typical chemical slag and sulfur attack on the refractory material is getting enhanced by the presence of arsenic. This work deals with post-mortem investigations of a magnesia-chromite brick and castable used in copper smelting furnaces showing an additional and increased chemical attack by arsenic.
