(1) The size distributions of diaspore, kaolinite and limonite ground in a ball mill in turn were studied.

(2) However, assimilation of limonite is better and the capability of creating calcium ferrite is higher by 20% than other ores. The reducibility of limonite is better.

(3) Mineral resources of coal, red siderite, limonite, chromite, gold, copper, limestone, gypsum and so on.

(4) Kinds of heavy minerals, magnetite, amphibole, epidote, limonite and so account for 81% and have their presence in all stations.

(5) The main metal minerals include limonite, hematite and jarosite, and the gangue minerals are dominated by quartz, feldspar(/limonite.html), sericite and clay minerals.

(6) Limonite ore is one of the complex refractory ores and has a low utilization rate.

(7) The contents of organic material, limonite and manganese hydroxides influence the variation of ore element.

(8) The main silver-bearing minerals were psilomelane, pyrolusite, limonite, galena, pyrite and sphalerite.

(9) The ore occurrences in phacoidal. gold - bearing limonite cap is overlimed in the pyrite ore body.

(10) Glauconite, hematite - limonite and some chlorite are formed in syndiagenesis.

(11) To separate hematite, supposed hematite, specularite, limonite, siderite, manganese ore, chromite and so on.

(12) There are two major ore types, namely, oxidized ore dominated by gold -bearing limonite and primary ore dominated by gold-bearing pyrite.

(13) The pyrite and siderite associated with the ores have been oxidized into limonite, hemitite and goethite.

(14) In the condition of laboratory test, sintering experiments were carried out with full limonite blend.

(15) It's a mid scale and its ore belongs to low grade structural altereds tyle, limonite, pyrite are mainly gold carriers.

(16) The directly sign of deposits is that the contact-belt of magma with stratums , the areas where have been had the mineralization such as molybdenite, pyrite, chalcopyrite, silicon, limonite and so on.

(17) The mineral components of nodules are mainly pyrolusite, psilomelane and limonite.

(18) Main metallic minerals in the manganese-silver concentrate were psilomelane, pyrolusite , pyrite, limonite, and a few arsenopyrite, hematite and sphalerite.

(19) A novel process was developed to treat the high - aluminum limonite ores.

(20) Under weathering carbonates, such as siderite are usually turned into limonite which finally occur as hematite in the Weathering crusts.

(21) The article indicates that there is genesisly relation between siderite ore and limonite ore.

(22) Metallic mineral excepting this native gold and native silver, as well as pyrite, stibnite, cinnabar, scheelite, dalarnite, magnetic iron ore, limonite.

(23) There are 46 kinds of fragmental minerals. The 67% of heavy minerals is magnetite, ilmenite, limonite and schistose minerals.

(24) An oxidized zinc ore from Inner Mongolia was found to be very difficult to treat due to its features of high oxidation rate, heavy weathering and the intimate association of hemimorphite and limonite.

(25) The typical characteristic of the ore is low sulfide. The metallic mineral has very few content (1%-2%), The mineral of ore is mainly of pyrite, chalcopyrite, limonite, aurum and electrum etc.

(26) For processing fine, feebly magnetic minerals, such as hematite, limonite, ilmenite, wolframite, tantalumniobium, red sludge and etc.
