Deskripsi Proses PEMILIHAN DAN URAIAN PROSES

3. Pemisahan dan Pengambilan Produk

Produk kering yang keluar dari RD-01 pada suhu 60 °C kemudian disimpan dalam Silo untuk kemudian diangkut ke konsumen dengan kapal maupun truk khusus. Limbah yang dihasilkan berupa padatan atau lumpur yang berwarna kemerah-merahan dan cairan yang mengandung sedikit asam. Limbah padat ini kemudian ditampung dalam bak penampung limbah sampai dingin dan mengering untuk kemudian dapat dibuang ke lingkungan atau untuk memperbaiki lingkungan tempat penambangan biji bauksit.
