Year of Completion
Sumbawa Jutaraya (SJR) was proposing to develop the Pangulir Gold Project which
was classified into oxidation domains of Oxide and Sulphide. About 25 % of
deposit was to be distributed as oxide and 75% as sulphide ore. The Pangulir
gold processing plant planned to consist of Comminution, Gravity (centrifugal
concentration) and cyanide leach with carbon adsorption (CIL) Circuit.
Additional pretreatment circuit was prepared to anticipate the refractoriness
of Sulphide ore which can only recover < 80% Au. The pretreatment circuit
consists of Flotation and Roasting circuit.
was engaged by PT. Sumbawa Jutaraya (SJR) to provide engineering services and
associated deliverables for Basic Engineering Design (BED) to Feasibility Study
level associated with Pangulir Gold Project Process Plant
