METHOD OF FORMING TACONITE PELLETS WITH A DOUBLE SULFATE SALT BINDER

摘要

Taconite fines are pelletized by adding to the taconite 2 to 4 percent by weight of a double salt of potash-magnesia, preferably dissolved in an amount of water equivalent to about 10 to 15 percent by weight of the taconite. The resulting mass is mixed and formed into pellets by granulation or briquetting techniques. The pellets are allowed to cure and then dry to a water content of about 1 to 2 percent.
