Secondly, the SAG mill loading process is a 'high inertia' process that can be approximated as an integrating process. This means that it is open-loop unstable. The hybrid control strategy presented implements an advanced 'load stabiliser', which transforms this integrator process into a more manageable first order process, which can be steered stably against the constraints. SAG mills are still of major importance, but I asked the question at Comminution '12 whether ball mills would play a significant role in comminution circuits, or would they be superseded by SAG mills.Chris Rule, of Anglo Platinum, felt that rod mills would play an insignificant role, as they are severely limited in terms of size, and ball mills may play a diminishing role as the upper feed

Our Bulletin 1608 DySC Voltage Sag Protectors protect against voltage sags and momentary outages that account for a significant amount of manufacturing downtime and damaged equipment. These DySC protectors do not require batteries, they have no moving parts, and they require minimal maintenance.
A SAG mill liner issue at Independence Group's Nova nickel operation in the Fraser Range of Western Australia has seen the miner miss its annual production guidance for the financial year. The problem, which saw a reduction in processing plant availability in the second half of June, resulted in an 800 tonne shortfall in nickel output, Independence said.

The larger particles from this mill are returned to the S.A.G. mill for more grinding. The finer particles receive more grinding in a ball mill, and are size classified to give a final product of 80% microns. See more detail on grinding and sizing 5. Leaching and
Comminution is performed in low aspect ratio semi autogenous (SAG) grinding mills applying high chrome grinding media with typical sequential grind sizes of 60% and 75% passing 74 microns. With such a low base-metal sulfide, successful flotation recovery of the platinum depends on the flotation of gangue minerals to stabilize the froth till the last stages of cleaning.

Spencer et. al. (1999) have been studying SAG mill monitoring with acoustic emissions. It has been shown that measurement of acoustic emissions can be used as a part of a system for both process control and condition monitoring of SAG mills.
3, and also contained many platinum group metal. The mineralogical data confirmed that in this Cu/Ni sulphide ore, copper mainly existed in the form of chalcopyrite. 2.1.2. Reagents The depressant sodium alginate [SAG, MW 32000~200000, the viscosity of

Platinum-group metals (PGMs) occur in a layer averaging 2.4m-thick and are associated with pyrrhotite, chalcopyrite and pentlandite. As of December 2019, Stillwater is estimated to contain mineral reserves of 26.8Mt at a grade of 19.4g/t containing 16.7Moz, while East Boulder is expected to hold 21.5Mt of reserves at 14.7g/t with 10.2Moz of contained PGM.

Hey guys! So I'm posting a (in my mind) a difficult question to find an answer to! I'm a 4th year at an engineering school studying Aerospace Engineering. Part of our education is a senior project, which the whole class participates in. The prompt for the class this
2012/9/30Ferrous ore in a Pulverizer or a Sag Mill has a chance to produce Shiny dust. If You want maximum efficiency though, pulverize silk-touched Redstone Ore for Cinnabar (or transpose some gelid cryotheum into cinnabar ores) and smelt that Cinnabar with Ferrous in an Induction Smelter for (or more with augments) shiny yield.
The platinum-group metals (abbreviated as the PGMs; alternatively, the platinoids, platinides, platidises, platinum group, platinum metals, platinum family or platinum-group elements (PGEs)) are six noble, precious metallic elements clustered together in the periodic table. These elements are all transition metals in the d-block (groups 8, 9
