The objective of this research is to determine the rare earth elements (REEs) from themonazite minerals content of several tin tailing sands (TTS)of ex-tin mining area in Kuala Raya Singkep Island, Indonesia. We used the energy dispersive analysis of &nbs... see more

Sebagai sisa kegiatan penambangan timah, tailing mengandung mineral-mineral seperti pirite (FeS2), marcasite (FeS2), dan galena (PbS) yang menyebabkan tanah menjadi asam. Rendahnya kadar asam (pH) menyebabkan tambang TN 1.1 Air Lekok Mapur tidak memiliki ... see more

Efektivitas bintil akar kedelai edamame dipengaruhi oleh penggunaan pupuk sebagai sumber energi mikroba. Pemanfaatan kompos tandan kosong kelapa sawit (TKKS) merupakan solusi alternatif pupuk organik. Penelitian ini bertujuan untuk mengetahui pengaruh kom... see more

The effects of salinity on the release of copper (Cu), lead (Pb) and zinc (Zn) in tailing sediment have been studied by stripping voltammetry. The purpose of the research is to know the effect of salinity on the release of metals with certain pH, conducti... see more

In the process of producing bitumen from oil sand, a by-product called tailings is produced. Tailings are a mixture of clay, fine particles, water, solvent and residual bitumen. The industry’s current approach is to leave them in tailings ponds; however, ... see more

Using vanadium extraction tailings as an iron source and glucose as a template, hollow spheres of Fe2O3 were successfully synthesized via hydrothermal synthesis for methyl orange adsorption treatment. The phase and structure of the samples were characteri... see more
