01-10-2010· Nickel is commonly present in two principal ore types—sulfide or laterite. Sulfide ores are typically derived from volcanic or hydrothermal processes and usually include copper (Cu) and/or cobalt (Co), and often precious metals such as gold (Au) or platinum (Pt), palladium (Pd) and rhodium (Rh) (the platinum group metals or PGMs) (Naldrett, 2002, Hoatson et al., 2006).
Nickel and copper are the primary metals, but we also produce cobalt and precious metals such as gold, silver, platinum and palladium. Our Raglan Mine facilities include four active underground mines, a concentrator, power plant, administrative and accommodation facilities, a …

One of the most used processes to treat nickel and cobalt "speiss" is that used by the company, Sherritt Gordon Mines Ltd, from Fort Saskatchewan, Alberta, Canada. Sherritt Gordon Process The nickel and cobalt metallurgy processes begin with an initial treatment of the mineral, re-concentrating it through crushing and flotation/gravity and obtaining a "speiss", rich in cobalt and nickel.
17-08-2020· The mining of laterites is basically an earth-moving operation, with large shovels, draglines, or front-end loaders extracting the nickel-rich strata and discarding large boulders and waste material. The ore is loaded into trucks at the face, as would be …
Nickel is obtained from two main types of deposits from the mineral garnierite (Ni-silicate) in nickel-rich laterite formed by weathering of ultramafic rocks in tropical climates. It also is mined from Ni-sulfide concentrations, mainly from pentlandite in igneous mafic rocks.
Metallic sulfide mining (aka hard rock mining) is the practice of extracting metals such as nickel, gold and copper from a sulfide-rich ore body. Sulfides are a geologic byproduct of mining in this area, and by exposing sulfides to the air and water in our atmosphere, sulfuric acid can be created — threatening to poison the nearby water, environment, and communities.
Nickel smelting is the process that nickel ore goes through to eventually remove impurities and leave just the nickel metal. While the ores can come from different stones and sources, they have two categories: lateritic, or rocks found in tropical climates and which contain nickel; and sulfidic ore, which is mined from underground.
11-09-2020· On top of that, with nickel being one of the most technically challenging metals to process and refine, and every operation being unique, further challenges will also be asset dependent (Exhibit 1). For miners, the type of ore deposit—sulfide or oxide (or laterite, further subdivided into saprolites and limonites)—defines the whole value chain.
Nickel Processing '12 | A Blog for Browsing Mining, Mineral ... Nickel Processing '12 November 27, 2012 Report of the processing of nickel ores and concentrates '12 available on the following link.
Mixing-preferably Flotation Process: Copper nickel can be get from raw ore, then the copper concentrate with low grade nickel and the nickel concentrate with low grade copper can be separate from the mixing concentrate, the nickel concentrate will be sent into the next stop-smelting, nickel matte can be get and then it will be separated.
15-02-2019· Nickel and its compounds get into the atmosphere through natural processes, such as the spread of dust and volcanic eruptions by the wind, as well as through industrial activities. The general public may also be exposed through nickel-plated materials, such as coins, jewelry, and stainless steel cooking and eating utensils.
21-06-2021· MINING.com Editor | June 21, 2021 | 12:06 pm. BHP's Nickel West operation. ( Image courtesy of BHP. ) Nickel's primary purpose is for the production of stainless steel, but the metal also ...
22-06-2018· The mining process can be broken down into two categories: Surface Mining. Workers begin by striping the overburden, which is rock, soil, and ecosystem that lies above the surface. Underground mining. The digging of tunnels and sink shafts when …
Nickel: smelting; Extraction and purification; Nickel is recovered through extractive metallurgy: it is extracted from its ores by conventional roasting and reduction processes that yield a metal of greater than 75% purity. In many stainless steel applications, 75% pure nickel can be used without further purification, depending on the composition of the impurities.
20-03-2019· The extraction of nickel process generally consists of crushing, sieving, washing, re-selection, grinding, and slurry concentration, or the nickel leaching method. The target element nickel distribution varies with the nature of the ore, mostly contained in fine-grained grades.
12-07-2021· The project involved open-pit mining from three nickel deposits, and a hydrometallurgical process plant to produce up to 50,000t of contained nickel and 1,400t of contained cobalt per annum in a mixed hydroxide intermediate product (MHP) for further processing at BHP Billiton's Yabulu Nickel Refinery in Queensland.
List of NICKEL mining companies with access to company profiles, projects, resources and reserves and technical analysis.
06-08-2021· One process is the ammonia pressure leach, in which nickel is recovered from solution using hydrogen reduction, and the sulfur is recovered as ammonium sulfate for use as fertilizer. In another, the matte may be roasted to produce high-grade nickel oxides; these are subjected to a pressure leach, and the solution is electro- and carbonyl refined.
29-04-2018· The most common issues of environmental contamination are emissions of acid rain-causing sulfur dioxide to the atmosphere, acid mine drainage (17) and heavy metals contamination in soil and water. The use of recycled metals does reduce the overall impact of mining and processing nickel, but increasing global demand will continue to drive land ...
NICEL MINE OTT T Nickel mining Nickel-containing ores are currently mined in more than 25 countries worldwide. The Asia Pacific region accounts for more than 70% of global nickel mine production. Indonesia, the Philippines, Russia, Australia and Canada are the biggest nickel producers. While mine production in Canada and Russia is mainly linked
The processing plant can process up to thirty thousand tonnes of marketable chromite sand monthly. Exploration Evaluation and assessments of Small Scale Mining Permit (SSMP's), Exploration Permits Areas (EP) and Mineral Processing Sharing Agreement (MPSA) License areas were conducted by CCILMMRC for Chromite within the entire Zambales Province.
Processing. After mining, nickel ores are further processed to upgrade their nickel contents from 1-4% typical of the ores to concentrates with grades in the range 10-20%. Concentration involves crushing the ore and separating nickel-bearing from other minerals using various physical and chemical processing …
Nickel mining in Indonesia began with small-scale exploratory mining operations during the Dutch East Indies era and began to expand in the 1960s. Most of Indonesia's proven nickel reserves are located in the islands of Sulawesi and Halmahera, and the country has the largest annual production and reserves of nickel in the world.
Mining activities are anticipated to begin in October 2020, with commissioning of the processing plant scheduled for July 2021. The mine is expected to produce 53,300 tonnes per annum (tpa) of nickel sulphate, 89t of scandium oxide, and 8,500tpa of cobalt sulphate during its mine life of 18 years.
