The two most commonly used devices for size reduction are the crushers and grinding mills. The crushers are normally fed with rocks, up to about 1 meter in size, while the grinders are usually fed with rocks crushed down to a maximum size of about 50 mm. Larger rocks produced at the mines are initially separated by grizzlies, broken by hammers ...
Ilmenite is brittle and dense. Due to the physical and chemical properties of mineral surface, it is not easy to recover coarse ilmenite by flotation process. However, fine or fine ilmenite has good floatability and can be recovered by flotation method. 1. Flotation Process 1) Conventional flotation method. In the conventional flotation process ...

Ilmenite charges blended with coke and soda ash were smelted in an electric arc furnace to remove most of the iron as metallic iron and to prepare slags with different FeO levels for sulfation-leaching tests. Pelletized and ground slag charges blended with and without an Na2SO4 additive were reacted with equal proportions of SO2 and O2.

Panzhihua ilmenite, located in Sichuan, Southwest China, is one of the largest ilmenite reserves over the world and about 90% of the total resource in China. However, its high impurity content (MgO > 6%) makes it unsuitable for chloride TiO 2 pigment production and can only be processed by the sulfate process.
2 pigments (into China) grew by 10 - 20 % per year. NOTE: • The growth in China comes from Sulphate route pigment plants that mainly use Ilmenite as the feedstock (a process that can also use some quantities of TiO 2 Slag).
The diagram shows the production of titanium dioxide via the sulfate process[/caption] Ilmenite processing. Initially, ilmenite ores are dried to a moisture content of less than 0.1% and ground to give a mean particle size of less than 40 mm. This prevents heating and premature reactions downstream. The finely ground, titanium-bearing ore is ...
sulfate process involving concentrated sulfuric acid tolerates low-grade ilmenite with a feedstock comprising a nely ground ilmenite concentrate of a minimum 44 TiO 2 or a sulfatable titanium slag of 78 TiO 2, the process is environmentally hazardous and the byproduct iron sulfate is considered as a waste.5 On the other hand, the chloride .
The ilmenite conversion process has been broken down into three general unit operations¬-reduction, smelting, and leaching—as shown in figures 8, 9, and 10. To see what actual flow-rates and energy requirements may be expected in a production plant, material and energy balance data from the 4.5- to 9.1-kg/h pilot plant were scaled to a basis ...
Ilmenite is converted into pigment grade titanium dioxide via either the sulfate process or the chloride process. Both Sulfate and Chloride Processes produce the titanium dioxide pigment in the rutile crystal form, but the Sulfate Process can be adjusted to produce the anatase form. Anatase, being softer, is used in fiber and paper applications.
Panzhihua ilmenite, located in Sichuan, Southwest China, is one of the largest ilmenite reserves over the world and about 90% of the total resource in China. However, its high impurity content (MgO > 6%) makes it unsuitable for chloride TiO 2 pigment production and …

Manufacture of titanium dioxide. There are two main processes, the Sulfate Process and the Chloride Process (Table 1) which use the two principal ores, ilmenite and rutile, respectively. Ilmenite contains 45-60% TiO 2 and rutile contains up to 99% TiO 2. The ores are mined worldwide but most production is in Australia and South Africa.
Disclosed is a novel fluorite purification method which can particularly reduce the content of arsenic in fluorite effectively. As is leached from a fluorite raw material containing CaF 2 and As by acid leaching (or mechanochemical acid leaching) in the presence of an acid while fracturing the fluorite raw material, thereby producing purified fluorite having a reduced arsenic content.

There are three major types of processing of brines in the production of anhydrous sodium sulfate; the Ozark-Mahoning process used in Vest Texas, Kerr-McGee's process at Searles Lake (Figure 2-13), and the process used by the Great Salt Lake Minerals and Chemicals Corp. in Utah. The Ozark-Mahoning process is shown in Figure 2-14.
LM Vertical Mill integrates crushing, drying, grinding, classifying and conveying together, and it is specialized in processing non-metallic minerals, pulverized coal and slag. Its coverage area is reduced by 50% compared with ball mill, and the energy consumption is saved by 30%-40% similarly.

The present invention provides a process for upgrading a primary ilmenite containing gangue mineral grains for forming titania pigment by the sulfate method the process including the step of roasting a primary ilmenite containing gangue mineral grains at a temperature of less than 650 176 C under conditions that promote the formation of a...
Sorelslag prepared by arc-smelting of ilmenite also is used commercially in the sulfate process to produce titania pigment. The Sorelslag, containing about 70 wt-pct TiO2 and 10 to 15 wt-pct iron oxide, still yields iron sulfate as a byproduct in the sulfate process; consequently, disposal problems are reduced but not eliminated.
