Introduction Taconite mining and processing on the Iron Range in northeastern Minnesota releases mineral fibers and particles that have been a public concern since the 1970s Higgins et al 1983; Axten and Foster 2021; Berndt and Brice 2021; Wilson et al 2021; Clark et al 1980; Cooper et al 1988 1992; Gamble and Gibbs 2021 Taconite is a hard dense sedimentary rock that contains
The slurry from the rod mills is then pumped to the magnetic separators that separate the iron bearing materials from the non iron particles called tailing The magnetic ore slurry is then transferred to the ball mills that further reduce the ores to fine powder 30 µm
If magnetite is the principal iron mineral the rock is called magnetic taconite; if hematite is the principal iron mineral the rock is called hematite taconite oxidized taconite or non magnetic iron grade ores such as taconite ore is fine ground in a rod and ball mill not shown so
Development of an approach to the simulation of size reduction/mineral liberation for magnetic taconite ore in tumbling mills and its implementation in a BASIC computer program ball and rod
All of the ore was ground in the AMMTEC pilot AG mill m diameter inside liners and m EGL and then run through the magnetic separator To protect the magnetic separator the AG mill was closed with a 1 mm screen In the full scale plant it is intended that the AG mill will
31/12/1996 · A commercial high pressure roller press KHD 90/25 was installed at the Coleraine Minerals Research Laboratory for testing in October 1994 Pilot plant evaluation of the high pressure roller press has shown that it can be used as an alternative to the rod mill for the comminution of taconite A series of pilot plant tests were run to compare
The primary rod mill discharge at about minus 10 mesh is treated over wet magnetic cobbers where on average magnetic taconite ore about 1/3 of the total tonnage is rejected as a non magnetic tailing requiring no further treatment The magnetic product 911metallurgist
01/02/2021 · More than 90% of the fluoride present in rod mill feed is rejected with tailings during size reduction and magnetic separation The furnace tests demonstrate that bentonite and fluxstone calcite and dolomite addition to taconite concentrate during pellet production increases the amount of fluoride that volatilizes during induration
