Analisis Kualitas Air Lindian Sisa Pengolahan Nikel (Ferronickel, Nickel Matte Dan Nickel Pig Iron)

Abstract

Slag merupakan limbah hasil pengolahan nikel yang dapat mencemari lingkungan perairan yang disebabkan karena limbah slag tersebut dapat terlindi oleh liquid. Tujuan penelitian yaitu mengetahui kualitas air lindian slag ferronickel, nickel matte dan nickel pig iron. Metode yang digunakan dalam penelitian yaitu uji kinetik (Free Draining Column Leach Test), uji sifat fisik dan kimia. Pengambilan data menggunakan alat intelegent meter, Atomic Absorption Spectroscopy (AAS) dan X-ray Flourosence (XRF). Diperoleh hasil penelitian dari tiga sampel air lindian yaitu slag ferronickel, nickel matte dan nickel pig iron. Air lindian slag ferronickel diperoleh parameter-parameter dengan nilai pH 8,24,

Analysis of iron content in the leaching process of nickel slag as raw material for manufacturing fero sulfate

“…This experiment was conducted to determine the effect of sulfuric acid concentration and time on the amount of dissolved Fe. So that the effectiveness of the concentration of acid that can dissolve the most iron content can be obtained nickel slag waste (Majalis et al, 2020;Rambu et al, 2021).…”

“…One of the industrial fields that continues to develop is the nickel smelting industry, the impact arising from these industrial activities is the problem of waste. This issue has recently received attention from the government or national and international environmental agencies (Rambu et al 2021).…”

“…Growth Java Industry which is stockpiling slag waste in open land. Slag waste can cause environmental pollution, especially the problem of changing the quality of surface water and ground water (Rambu et al, 2021).…”
