Jun 05, 2012· So I live in northern Florida. I am building a small cottage along with a small horse stable. My first thought was A stone and mortar building. Coming from Utah I assumed stone would be readily available. That was not so, I found only two medium size rocks on our entire 5 acre property both of which were falling apart. I started combing the internet for alternatives when I found Cobbing.

The simulations show that the net throughput from the circuit at a coarse–hard feed will be ≈10% higher compared to a situation when the feed is fine–soft. Moreover, a fine and soft feed results in a coarser particle size distribution of the mill discharge, compared to a coarse and hard material.

The tests indicate that the lean-grade ore types (lc2 and lc5) lend themselves to dry magnetic cobbing, producing an enriched concentrate with noticeable upgrading. Additionally, the coarser size of those lean ore types produced the higher grade magnetic iron.

Low Intensity Magnetic Separators (LIMS) Dry lowintensity magnetic separation is confined mainly to the concentration of coarse sands which are strongly magnetic, the process being known as cobbing, and often being carried out in drum separators. Below the 5 mm size range, dry separation tends to be replaced by wet methods, which produce much ...
> Milled FeSi produced in different size ranges – 30-95% –45µm – Coarser, low viscosity grades achieve medium densities of up to 3.3 > Atomised FeSi – More spherical particles – Medium is of lower viscosity – Used to achieve densities as high as 4

Stora Sahavaara ore. Coarse cobbing testwork showed only slight weight rejection with minimal Fe losses. The grind requirements for the secondary LIMS stage was investigated through Davis tube tests at different grind sizes as presented in Figure 2. Both SiO 2 and MgO are impacted by grind size. As suggested by Cline and René Rosas
wwith the cobbing product to feed the ball mill circuit. The addition of a REDS scavenger improves yield due to the recovery of additional mass of fully liberated haematite wwhich is not recovered across the cobbing LIMS because of its lower magnetic susceptibility.

Lims belt drums has variable speed for optimal separation. The BSA-type has magnetic poles arranged in rows parallel to the drum shaft, thus forcing the magnetic material to rotate when passing over the drum causing the rejection of non-magnetic and weakly magnetic material. The BSA-type is suitable for separation of particles up to 200 mm in size.
magnetic separation (a process known as ‘coarse cobbing’)at a very high mass recovery and a total iron yield of 63% and 84% respectively. • The coarse cobbing concentrate specification is significantly coarser than the 150 micron grind size concentrate modelled in the 2011 Scoping Study which requires a
