Qazib olingan foydali qazilmalarni turli xil usullar orqali boyitsh imkoniyati mavjud. Rudalarning fizik va kimyoviy hususiyatlari qarab tanlanadi. Zichligi katta bo’lgan minerallarni gravitatsiya usulida, sulfidli rudalarni flotatsiya usulida, mineral zarrachalarning magnit hususiyatlari inobatga olib magnit usuli tanlanadi.
