Abstract: Method for extracting precious metals from their ores in which the ore is particulated and mixed with a binding agent to form a paste. The paste material is discharged into a rotary drum at an extruding station where it is pelletized by forcing it through a perforated sidewall of the drum. The pellets are discharged onto a conveyor belt and are transported to a spray station where they are wetted with a lixiviant solution. The lixiviant coated pellets are then dried by exposure to a heated air stream at a drying station as they are transported to an open air curing stockpile. The cured pellets are heaped in a pile and are then washed with a water spray to yield a pregnant solution of a precious metal salt.

Abstract: This specification discloses an improvement in a pellet mill having a cylindrical feed receiver clamped to a radially perforated and cylindrical rotatable die. Rollers are disposed interior of the die for extruding feed through the perforated die into pellet form, the die being connected with a supporting cartridge by a ring clamp. The cartridge has an annular groove extending peripherally around a flanged portion, and an intermediate element is inserted in the groove to form a bearing and wear translative surface that engages the clamp.
