Abstract. A research team from the University of Utah is working to make inroads into saving energy in these SAG mills. In 2003, Industries of the Future Program of the Department of Energy tasked the University of Utah team to build a partnership between the University and the mining industry for the specific purpose of reducing energy consumption in SAG mills.

At current gold prices this is worth about US600. Both smelter treatment charges and oxidation or bioleach costs are at least 200/t of concentrate and payables/recovery in the 90% range, so a minimum GSR for effective downstream processing is around Clearly this is a function of gold price, but in the current gold price and cost ...

surveys were executed and samples of key streams obtained, including belt cut samples of the SAG mill feed. The Paddington comminution circuit is a conventional SABC circuit consisting of a 24 ft. diameter SAG mill ( MW) and a 15 ft. diameter ball mill ( MW). Cyclone overflow (O/F) is sent downstream for gold leaching.

Publisher Summary. For the vast majority of ounces of gold produced, comminution costs in the form of power, grinding media, and liners represent the single largest cost category of milling. Since, semiautogenous grinding (SAG) ballmill circuits represent the single largest type of gold milling comminution circuits, the chapter focuses on SAG.

The process flow incorporates two SAG mills, a ball milling circuit, cyanide leaching and a carbon in pulp (CIP) plant. Loaded carbon is transported to the central Elution Circuit at D1 Plant. The D1 Plant was commissioned in 1972 as a three stage crushing, two stage milling, filtration and zinc precipitation operation.

1. SAG mill is the primary tool for grinding. SAG mill is used before the other mills. Ball mill is a secondary, and it is used after the SAG mill. 2. SAG mill breaks the raw material into pieces for the further grinding. Ball mill is used to grind the pieces of raw material into. powderlike structures. 3.

The two main objectives for a grinding process are: To liberate individual minerals trapped in rock crystals (ores) and thereby open up for a subsequent enrichment in the form of separation. To produce fines (or filler) from mineral fractions by increasing the specific surface.
