Rotary coolers for optimised material processing

Similar to a direct rotary kiln, our direct rotary cooler utilises a counter-current method of cooling materials, via a stream of ambient or chilled air. This material processing equipment is both highly durable and versatile, as it can cool a large variety of hot

Nickel processing Extraction and refining Britannica

1 天前 These are carried out in large rotary-kiln furnaces. Dryers 50 metres long and 5.5 metres in diameter are common, while reduction kilns 5 to 6 metres in diameter and more than 100 metres long are required to handle the large tonnages of ore and to provide the necessary retention time. Next, it is necessary to reduce the oxide to nickel

Operational Overview QUEENSLAND NICKEL SALES

The ore is reclaimed and moved along a conveyer system and fed to three rotary driers to remove moisture. The dry ore is fed into ball mills, where it is ground to a fine powder. After the grinding process, the fine ore is mixed with fuel oil reductant and fed into 12 multi-hearth furnaces where the nickel and cobalt compounds are reduced at

2015-2-27 gas, etc.) as a reductant in a rotary kiln. Nickel and cobalt are firstly reduced because iron has greater affinity to oxygen. The product is charged to converter for refining after discarding the slag phase containing unreduced iron oxide, magnesium oxide and silica. The end-product is ferronickel alloy which contains 25% of nickel.

PT ANTAM Tbk Nickel

Nickel ore is one of ANTAM’s important products. ANTAM produces and exports high grade nickel ore with a minimum 1.8% nickel content and a maximum 25% iron content (saprolite) and low grade nickel ore with a 1.2% minimum nickel content (limonite) and minimum 25% iron content. ANTAM’s nickel ore mines are at Pomalaa, Tanjung Buli and Gag Island.

The calcined ore was processed in a DC-arc furnace, without operational problems, over a period of 32 hours. The overall nickel recovery to the alloy was 98% and the residual nickel in the slag was less than 0.07 percent by mass. Test 2:

Ferronickel an overview ScienceDirect Topics

The smelting of ferronickel using lean nickel ores usually starts with roasting (calcining) of the ore mixture with limestone (~one third of the ore), anthracite (~1/10 of the ore amount), and recycled dust. Roasting is carried out in rotary kilns (~3 m in diameter, ~75 m in length, with a hot zone length of 9 to 12 m in the case of lean ore processing).
