Abstract

Abstract Indonesia is one of the largest tin producers in the world. The by-products of processing tin ore in the form of tailings are not used properly. Based on several studies, tin tailings have high levels of silica. In this paper, a silica purification study from tin tailings is proposed using a solid-state method at different pH. The purity of silica in this paper is determined by XRF and XRD analysis. This research is expected to increase the economic value of tin tailings, which can be utilized in various applications.
