Facts Interesting
- Sumber utama Kobalt minangka produk sampingan saka pertambangan logam tembaga lan nikel.
- Logam kobalt bisa dipikolehi saka unsur liyane kayata Oksigen, Sulfur lan Arsenik.
- Uga digunakake ing proses electroplating amarga nuduhake sifat anti cession.
- jeneng asli Technetium ana masurium.
- Ing wektu nemokaké iku ditemokaké ing sampel Molybdenum.
sumber
Found in Senyawa, Mining, Ores saka Minerals
