RKEF treatment produces either FeNi or NPI or, but less commonly in an Indonesian context, nickel matte through the addition of sulphur. Each production line of the RKEF process consists of two rotary kilns and an electric furnace. The first kiln is for drying of the ore, the second completes the drying process and reduces the ore too.
A rotary kiln is a long tube that is tilted (to the horizontal plane) and rotated, and the diameter of the kiln may be fixed or variable. Low tilt angles (3–4°) are utilized in this variety of kilns (Esence et al., 2020 ). The tilt angle and …

ROTARY KILN CONSTRUCTION. While FEECO rotary kilns are custom designed around the material to be processed, in general, there are some standard components that serve as the basic design of a rotary kiln. The diagram shown on page 8 illustrates some of the …
The rotary kiln-electric furnace process accounts for two-thirds of the global nickel output. The raw laterite nickel ore contains approximately 1–5 wt.% Cr2O3, but its recovery is limited during smelting. Due to the inefficient utilization, the accumulated Cr-containing slags are potential environmental risks. This work provides positive results …
NPI is a low-cost feedstock for stainless steel production when used as a substitute for electrolytic nickel. The existing commercial NPI production processes such as blast furnace smelting, rotary kiln-electric furnace smelting, and Krupp-Renn (Nipon Yakin Oheyama) processes are discussed. As low-temperature (below 1300°C) reduction of ...
Since laterite ores are not generally amenable to significant upgrading by mineral processing techniques, saprolite is treated pyrometallurgically, typically by the Rotary Kiln Electric Furnace (RKEF) …
Featuring eight lines of rotary kiln-electric furnace ferronickel processing capacity, the Bahodopi facility is estimated to have an annual production of 73,000mt of nickel. While PTVI will have a 49% stake in the JV, Baowu and Xinhai will jointly own the remaining 51% interest.
27/01/22. The Angel Nickel project at Halmahera island in Indonesia has entered its commissioning phase with the first of its four rotary kiln electric furnace (RKEF) lines having started nickel pig iron (NPI) production. All four RKEF lines are expected to be operational by the end of April as the project ramps up towards its 36,000 t/yr ...
Bijih nikel yang telah dipisahkan kemudian dimasukkan ke dalam pengering putar atau drying kiln bersama-sama dengan bahan atau materi lainnya.

The rotary kiln is used in many solid processes, including drying, incineration, heating, cooling, humidification, calcination and reduction. This widespread application can be attributed to factors such as the ability to handle varied loads, with large variations in particle size [1]. The rotary kiln is a slightly inclined steel cylinder that ...
The advantages of the rotary kiln are: (1) uniform heating and high heat transfer efficiency. The solid materials are heated in the uniformly rotating cylindrical kiln body, which move reversely against the gas; (2) large equipment scale, high operation continuity, and large production capacity; (3) stable product quality; (4) low energy …
Many Chinese nickel plants are government owned and, except for Jinchuan and several other smelters, the rest operate a Rotary Kiln Electric Furnace (RKEF) plant producing Nickel Pig Iron (NPI), with or without a captive steelmaking complex, have started only during the last two decades.
