3. Laterite nickel mines are proced in Indonesia and the Philippines. High grade nickel content of more than 4, this taste is generally purchased by Japan. The normal nickel content that can be purchased in China is between 1.8 and 2. That is to say, this range is the mainstream of laterite nickel market in China.

1、 Content overview

the material composition of the laterite nickel ore is analyzed. The grain size distribution of the original ore sample is mainly below 0.075 mm or 0.04 mm. The main minerals of nickel are silicate minerals and oxide minerals. The Philippine laterite nickel deposit is a nickel silicate deposit formed by long-term weathering and leaching of basic and ultrabasic rocks after serpentinization alteration. It is difficult to study the mineral composition because of its complex composition, fine grain size, poor crystallization, serious mixing and broken. According to the process mineralogy, the nickel minerals are identified as nickel serpentine, nickel cobalt clay, nickel manganese ore and nickel pyrite; The nickel bearing minerals include serpentine, chlorite, limonite and yidingite

iron occurs in the form of limonite in laterite, which is weathered ultrabasic rock. Olivine, pyroxene and other minerals rich in low valent iron are oxidized and decomposed in the oxidation zone under the weathering of laterite, and low valent iron is transformed into high valent iron. The solubility of high valent iron minerals is very small, which is relatively stable in the oxidation zone, so it remains on the surface, making the upper ore contain more than 50% iron. At the same time, there are some by-procts of ultrabasic rocks in the ore body Chromite, chrome spinel, ilmenite, nickel silicate formed by weathering and cobalt bearing hard manganese ore make the ore become a special "natural alloy iron ore" rich in iron, manganese, nickel and cobalt, which can be directly used for smelting high-quality alloy steel

through the study on the technological performance of the ore, the gravity and magnetic combination method has a good effect on the enrichment and separation of chromite, and the chromium concentrate containing Cr < sub > 2 < / sub > o < sub > 3 < / sub > 33.18% and nickel ore containing Ni 1.96% and Cr < sub > 2 < / sub > o < sub > 3 < / sub > 0.65% can be obtained. The results show that the leaching rate of Ni and CO is higher at atmospheric pressure of 100 ℃ and 50% concentration of sulfuric acid for 1-2 H. In addition to the acid leaching (wet method) method for recovering nickel and cobalt, the low nickel iron method (pyrometallurgical method) has high recovery rate, simple process and low cost; After rection roasting, crushing, grinding and magnetic separation, low nickel ferroalloy concentrate can be obtained. The recovery of valuable metals is 99% Ni, 92% Fe and 97% Co

Application scope and application examples this technology has carried out detailed tests and tests on the state of nickel, chromium and iron and the technological performance of ore utilization through the research method of process mineralogy, which will play a certain reference role in guiding proction and scientific research of mineral processing
