Laterite ores About 45% of the nickel for the stainless steel in It is noteworthy that laterite ores account for over dustry originates from reprocessing of scrap which, twothirds of the worldwide reserves for important non apart from the contained nickel, is important due .
grade and composition of chromite and laterite ores are the main factors to produce the alloy. The smelting of 1013% SCO chromite ore and 87 – 90% LIM laterite ore produced alloys with average iron, nickel and chromium content about 82%, % and %, respectively, at an average iron, nickel and chromium recovery of 98%, 97% and 87%,

%, the nickel laterite ore was called middle grade ore, and the nickel laterite ore, which the content of nickel was more than %, was called the high grade nickel laterite which had low iron content and more SiO 2 in the gangue. Laterite nickel ore was mainly distributed in tropical countries, within 30 degrees in north and south of
Abstract. The preparation of ferronickel alloy from the nickel laterite ore with low Co and high MgO contents was studied by using a prereduction–smelting method. The effects of reduction time, calcination temperature, quantity of reductant and calcium oxide (CaO), and pellet diameter on the reduction ratio of Fe and on the pellet strength were...
Mar 06, 2019· Class 2 nickel from nickel laterite ores can be converted to nickel sulphate however it requires high pressure acid leaching [HPAL], which is expensive with much larger CapEx requirements.

Nickel and associated metal values are traditionally recovered from ores by mineral processing, smelting and refining processes. Associated host minerals contain nonferrous metals such as copper, cobalt, precious metals such as gold and silver, and the platinum group of metals.
Nickel is an essential alloying element in austenitic stainless steel and other speciality alloys. The drastic increase in production of such alloys over the last decade, mostly because of economical growth of Asian countries, particularly China, has resulted in a considerably increased demand for ferronickel.
Laterites are formed by the weathering of ultramafic rocks and are a nearsurface phenomenon. Most of the nickel on Earth is believed to be concentrated in the planet's core. Nickel is primarily sold for first use as refined metal (cathode, powder, briquet, etc.) or ferronickel.
Chromite and laterite ores from local sources were smelted in a vertical tube furnace with activated carbon as reducing agent at 1400°C to 1550°C using graphite crucible under argon atmosphere. It is shown that the grade and composition of the ore are the main factors determining the feasibility of smelting a mixture of chromite and laterite ores to produce a FeNiCr crude alloy.
The smelting of nickel laterite ore is no different, as the smelting process is the dominant technique and is typically used to make nickel pig iron (NPI) for the Chinese stainless steel market. NPI is created by mixing, saprolite ores with coking coal and a mixture of fluxes.
Challenges. Nickel plants are some of the most complex metallurgical facilities in the world. A multitude of challenges and roadblocks can converge when companies try to design, build—and ultimately run—these mammoth operations. For executives and shareholders who scrutinize every capital expenditure and expect a return on every investment,...
