Studi pengaruh penggilingan kondisi kering dan basah terhadap kinetika dan karakteristik distribusi ukuran butir bijih sulfida kompleks galena sfalerit – Uji pendahuluan

Grinding is generally carried out in wet conditions, but issues regarding water conservation and high-water treatment costs encourage the application of grinding dry conditions. Both produce products with certain characteristics that affect success next process. P100 6 mesh (3.36 mm) ore was performed using steel ball media 33.33% solids for 5, 10, 15, 20, 25, 30 minutes. Particle size distribution product obtained from sieving process -200 (-75µm) particles were analyzed a laser diffraction particle analyzer. The Alyavdin kinetics equation model used to study behavior its consisting uniformity index, modulus fractal dimension studied logistic, Rosin-Rammler (RR) Gates-Gaudin-Schuhmann (GGS) model. Equivalent (EPS) specific surface area (SSA) observations on product. condition more effective reducing complex galena-sphalerite sulphide ore, indicated by high rate highest K value 0,135/minute, cummulative % undersize, low modulus, fine SSA compared grinding. Alyavdin's can describe galena sphalerite sulfide while follows logistic
