advantage of magnetic separation over flotation, in fine iron ore beneficiation is that treatment of 10 m iron ore is possible in flotation the feed is deslimed at 10 m and the 10 m stream is considered to be final tailings even though there is often a significant amount of contained iron ore.
ore in iron and steel industry, it is imperative to install beneficiation facilities to improve the recovery of saleable ores and to upgrade the feed material for ferro-manganese production. Manganese Ore Beneficiation There is a growing demand for richer ore with stringent stipulation of size in the domestic and international market.
The ore chemistry indicates that the massive hard ores and blue dust have high iron, low alumina and phosphorus contents. Because of high quality, these ores do not require any specialized beneficiation technique for upgradation.

ores are the most important and constitute a large proportion of world iron ore reserves2. In Kenya, Iron ore deposits have been documented to exist in laterites, in various parts of Kenya 3-5. Previous studies have shown that iron in laterites is fairly widely spread all over the country and contain 15 to 45 iron depending on source. Iron ...
Key words Iron ores, Mineralogy, EPMA, Geochemistry, Flotation 1. INTRODUCTION Although India is having vast reserves of iron ore, lack of consistency with respect to Al2O3SiO2 ratio makes these ores unsuitable to use directly in the metallurgical industries without prior beneficiation.

Various iron ore samples drawn from different mines and their mixtures were subjected to the test work. Results of pilot scale tests clearly indicate the superiority of flotation column vis-a-vis conventional cells and dual extraction column. Iron ore concentrate assaying 67 Fe and 2 Si02 and AI203 with a recovery of 85 - 90 could be ...
The important ores of iron are 1. Haematite, Fe 2 O 3 red oxide of iron 2. Magnetite, Fe 3 O 4 magnetic oxide of iron 3. Limonite, Fe 2 O 3.3H 2 0 hydrated oxide of iron 4. Iron pyrites, FeS 2. 5. Siderite or Spathic ore, FeCO 3. The cast iron is generally extracted from haematite Fe 2 O 3. The various steps involved in the process are ...
Currently beneficiation of hematite ores is conducted using either direct flotation hematite flotation or indirect flotation quartz flotation tech-niques depending upon the nature of the available ore bodies. In direct flota-tion, iron bearing mineral, mostly hematite, is floated using oleate as collec-
these iron-rich titanium ores in laterites has also been documented to be in huge amounts in Kenya. Titanium ores remain largely unexploited in Kenya since the current technology in use is very expensive and often requires a lot of water, a scarce resource, thus limited to only where we have large water bodies, in Kwale. Kenya is composed of 80 ...

Malachites are carbonate minerals also known as copper carbonate. Some beautiful specimens of malachite contain certain combinations with other minerals such as cuprite, azurite or chrysocolla. It also contains 2 atoms of oxygen and hydrogen - since these elements are the components of water, it is said that malachite is a hydrated carbonate.
