Tailings pond is a place for storing tailings or other industrial waste residues discharged from metal nonmetal mines after ore separation. The material will be into the stockpiling sorting and processing. hard to consolidate under natural conditions as result of high water content, resulting in certain safety risk pond. In this paper, tailing soil Huangshi City, Hubei Province studied triaxial...

Cibaliung Sumberdaya bergerak dibidang ekstraksi Salah satu proses emas di yaitu pelindian/ leaching . roses pelindian berlangsung selama 7 jam dalam tangki pertama (Tank CII. 01) dengan volume efektif 485 m Tangki tersebut dilengkapi sistem pengadukan (agitasi) berfungsi untuk memperluas kontak antara o...

BACKGROUND The positive matrix factorization is a powerful environmental analysis technique which has been successfully utilized to assess air-born particulate matter source contribution. The new version of this model (PMF5) has two additional estimation error methods and some other useful advantages compared to the previous versions. In the present study, the capability of PMF5 for identificat...

In transport experiments through columns packed with naturally Fe/Al oxide-coated quartz sand, breakthrough curves (BTCs) of natural organic matter (NOM) displayed strong and persistent power law tailing that could not be described by the classical advection-dispersion equation. Tailing was not observed in BTCs for a nonreactive tracer (sulforhodamine B); therefore, the anomalous transport is a...

Two different methods for predicting the quality of the water draining from a pyritic tailing are compared; for this, a static test (ABA test) and a kinetic test in large columns were chosen. The different results obtained in the two experimental set-ups show the necessity of being careful in selecting both the adequate predictive method and the conclusions and extrapolations derived from them....

In a magnetized inhomogeneous warm plasma having ionization/recombination, usual version of the KdV equation is found to be modified by two additional terms arising due to the inclusion of ionization/recombination and the density gradient in the plasma. The density gradient in the plasma shows its dependence on the ionization/recombination rate, ion-to-electron temperature ratio, obliqueness of...

The study investigated whether occupational accident risks were equally distributed across age categories over time in the context of production reorganization and work rationalization in a Swedish iron ore mine between 1980 and 1993. Three phases of reorganization, defined by productivity levels, and four age categories were related to age-related accident risk ratios using the Poisson-regress...

Controlled ribonucleotide tailing of cDNA ends (CRTC) by terminal deoxynucleotidyl transferase is a polymerase chain reaction (PCR)-mediated technique that was developed to facilitate cloning and direct sequence analysis of complete 5'-terminal unknown coding regions of rare RNA molecules. In contrast with standard tailing protocols using dNTPs as the substrate, ribo-tailing of cDNA ends is eas...

Reuse of process water in the flotation sulfide ores has crucial importance for environmental sustainability and improved economy. However, chemistry may be a critical subject efficiency as dissolved ion concentration increases with reuse. In this study, effects reuse on Cu-Zn ore were investigated. The flowsheet consists pre-flotation section to remove naturally floatable talc particles, seque...

Currently, approximately 1.4 billion tons per year of iron ore tailing wastes (IOT) are generated, mainly in Australia, Brazil, and China. This work describes the characterization application two typical IOT, i.e., fine coarse wastes. The physicochemical these IOT by different techniques such as XRF (X-ray fluorescence), XRD diffraction), Mössbauer spectroscopy, granulometry, indicates for a co...
