Control and Optimisation of a Gold Milling and Flotation Circuit The mill discharge circuit of Bjӧrkdal Gold Mine is ideally suited to an MPC solution, due to the limit handling that was necessary to accommodate the competing control objectives. The discharge sumps are integrated in a recycle through the gravity spiral separation circuit. Achieving a stable flowrate and pressure feed to the
Implementation of Computer Control on the Milling Circuit of ... The paper describes the implementation of a control strategy for the milling circuit at Buffelsfontein Gold Mining Company Limited. The milling plant is a material flow bottle-neck for the metallurgical operation, therefore the control objectives were based on the requirements of maximum tonnage throughput at a given consistent fineness of grind.
GRAVITY CONCENTRATION OF GOLD FROM CYCLONE FEED IN GRINDING ... Gold was subjected to the gravity concentration device in its coarsest state, i.e., as soon as a particle was discharged from the mill it saw the gravity concentration device. There were also some disadvantages: The gravity circuit had to process 3 or 4 times the new feed rate to the mill (the entire circulating load).

BATU HIJAU MILL THROUGHPUT OPTIMIZATION: MILLING CIRCUIT ... major milling circuit limitations for the purposes of this paper, in reality the issue is slightly more complex than summarized here). The higher ore BWi, the more frequent the milling circuit is Ball Mill limited (the year of 2013 was extreme one). The lower ore BWi, the milling circuit is more SAG Mill limited. an
GRAVITY RECOVERY OF GOLD FROM WITHIN GRINDING CIRCUITS Gold not only grinds six to twenty times slower than most minerals, it can even flatten and report to coarser size fractions. The long residence time of the gold within the grinding circuit can cause some of the GRG to become non-gravity recoverable due to smearing on to grinding media, mill liners and gangue minerals. This effect is minor as
Autoclave Circuit & Gold - Mineral Processing & Metallurgy Slurry from the grinding circuit, at approximately 35% solids and 80—85% passing 135 mm is pumped to three thickeners.
