  5. COMMINUTION Terdiridari : • Crushing : Jaw crusher, gyratory crusherdll • Grinding : Rod mill, ball mill dll Merupakan istilah umum yang digunakan untuk mengurangi ukuran bongkahan dari besar ke kecil. Mekanisme : ”energi kinetik berubah menjadi energi regangan dan panas melalui gesekan molekuler internal pada material yang dipukul”

  6. JAW CRUSHER BALL MILL

  7. SIZING Merupakan pengelompokan ukuran atau pemisahan material berdasarkan karakteristik ukuran yang berbeda. Terdiridari : • SCREENING : Grizzly, vibrating screen dll • CLASSIFYING : Spiral classifier, sizing classifier,dll

  8. GRIZZLY SPIRAL CLASSIFIER

  9. CONCENTRATION Merupakantahap pemisahan material berdasarkansifat, sepertisifat magnet, sifatlistrik, sifatpermukaan. Terdiridari : • Gravity concentration : Jig • Magnetic concentration : magnetic separation • Elektrostatic concentration • Flotation

  10. JIG MAGNETIC SEPARATION

  11. FLOTATION

  12. KESIMPULAN DenganPreparasiFisik, maka : • Mudahuntukmelakukanprosesselanjutnyapada material • Dapatmemisahkan mineral sesuaikarakteristiknya • Dapatmemisahkan mineral berhargadaripengotornya
