Bauxite recoveries in modern washing plants is in the range of 60–80%, however, in some of the plants, the recovery is found to be as low as 50%, as they use simple vibrating screens in place of hydro-cyclones. The quality of input bauxite, particularly silica content and targeted washed bauxite quality, dictate the washed ore recovery.
The reduction degradation characteristics of typical sinter, pellet and lump ore were tested with the reducing gas conditions simulating two kinds of iron-making processes. The results show that, in the same condition of gas composition and temperature, the reduction degradation degree (RDI <3.15 mm) of sinter is high, RDI …

Approximately 50% of the 10Mtpa–12Mtpa ore produced is processed at the mining area plants and the remainder at Point Central. SNIM markets several grades: 0mm to 90mm and 8mm to 30mm lump ores, sinter fines and high-phosphorus concentrates. In 2004, SNIM mined 10.7Mt of ore and shipped 11Mt of product, 14.3% more than in 2003.

many cases, ore with a total iron content of 60% to 63%, or greater, is regarded as high grade, and ore with a lower iron content is regarded as low grade. Ores are also classified as follows, according to their size and the processing method. - Lump: Ore lumps have diameters of approximately 10mm to 40mm and

ID 49046: National Certificate: Lump Ore Beneficiation, Level 3, 120 credits. ID 49044: National Certificate: Mineral Processing, Gold Extraction, Level 3, 124 Credits.
Iron (Fe) is a metallic element that constitutes 5.6% by weight of the Earth's crust and is the fourth most abundant element in the crust. Iron ores are rocks from which metallic iron can be economically extracted. The principal iron ores contain hematite (Fe 2 O 3) and magnetite (Fe 3 O 4 ). Hematite is an iron oxide mineral.
Typical applications include primary crushing of large lump ore in sampling stations and pilot plants, the pre-crushing of materials being prepared for analytical or metallurgical laboratory use, and in industrial production facilities. The JC5000 is suitable for soft to very hard ore, rock and large industrial particulate.
Screening is the process by which granulated ore material gets separated into different grades of particle size. In other words, it's a mechanical process that stratifies (divides) particles…
Table 1. Chemical compositions of three iron lump ores. The physical properties of the three lump ores are shown in Table 2. The open porosity of lump ore S was the largest, reaching 16.54%; the open porosity of lump ore J was the lowest, at 4.23%; and the open porosity of lump ore A was between the two, at 12.08%.
Goethite lump has good reducibility, but some susceptibility to reduction degradation. Decrepitation can be a problem in dense, goethite-bearing ore types. Water: Need for dewatering of wet processed fines. Handling properties – ores with high absorbed water can cause sticking and blockages in crushing and screening plants.
The plant features a primary crusher, secondary dry screening, and crushing and gravity separation systems. "The Hope Downs mine produced 33.79Mtpa of iron ore from open-pit operations in 2013." The plant can produce 47% lump ore and 53% fines.
Based on the particle size, iron ores are classified as iron ore fines (<10 mm) or iron ore lump (6.3–31.5 mm); iron ore fines are first processed in a sinter plant, while lump ores can be charged into the blast furnace (BF) directly. Iron ore lump is the lowest cost iron bearing material for the BF burden.
no accretion and no fused lump formation,. Metallization will be better compared to lump ore. There will be very much less fines in the product as against with lump ore. No need for crushing and screening of iron ore and resultant fines disposal problem No losses in handling iron ore as PELLETS will not break during transport or handling. 8
