Potensi dan Karakterisasi Limbah Metalurgi “Slag Nikel Pig Iron”

نویسندگان

چکیده

Pada beberapa tahun terakhir, pertumbuhan industri pengolahan material non fero seperti nikel, alumumium maupun tembaga berkembang sangat pesat. Hal ini secara tidak langsung berdampak terhadap peningkatan limbah metalurgi hasil tersebut. Di Indonesia, slag logam diantarannya Nikel Pic Iron (NPI) merupakan salah satu yang belum digunakan optimal. Disisi lain NPI diketahui mengandung unsur-unsur Pb, Zn, As, Cd dan Co berpotensi mencemari lingkungan membahayakan manusia. Upaya pemanfaatan menjadi produk lebih bernilai penting dilakukan untuk meningkatkan nilai ekonomi dari meminimalisir pencemaran lingkungan. Oleh karena itu, pada penelitian telah karakterisasi dikembangkan sebagai geopolimer. Karakterisasi menggunakan EDS mapping XRD slg dengan ukuran 200 mesh. Hasil menunjukkan bahwa terdapat fasa quartz, clinoenstatite, silimanite, calcium peroxide, olivine, forsterite, fayalite hypothetikal silika . Fasa tersebut terindentifikasi melalui puncak-puncak difraktogram sudut 20-70 o Selain mengindikasikan senyawa silika, magnesium oksigen tersebar diarea sama merata.

Effect of Pig Iron Slag Particles on Soil Microbial and Enzyme Activities

The effect of pig iron slag particles on soil physico-chemical, biological and certain soil enzyme properties was studied. Contamination of iron slag particles altered physico-chemical, biological and enzyme properties of soil. While soil pH increased slightly, electrical conductivity, carbon, potassium and phosphorus contents increased significantly in polluted soil. Contamination of soil with...

Electrochemically Enhanced Reduction of Iron Oxide from Slag

An experimental study was performed to measure the rate of reduction of iron oxide from calcia-silica-alumina slag by carbon in iron, and to determine whether the reaction rate can be increased by electrochemical means. It is shown that the reaction rate depends on both the ferric-ferrous cation ratio, and on the total amount of iron in the slag. It was observed that ferric cations are reduced ...
