Unprocessed nickel is what we call raw nickel, which is typically obtained straight out of the mine. Nickel often occurs in nature together with other elements like iron, arsenic or sulfur. The ore deposit is mined, crushed and then refined to give pure nickel as an element. This serves as a basic material for subsequent purification and manufacturing processes that lead to the creation of different products and alloys made from nickel needed for various industrial applications.
Definition and Properties of Nickel
Raw Nickel vs Nickel: What’s the Difference?
The difference between raw nickel and refined nickel is mainly in the means of their production and levels of impurities. Raw nickel, usually acquired directly through mining operations from its ore deposits, is not yet refined metal. It often contains other elements such as iron, sulfur or arsenic and impurities. Crushing, roasting and refining are some additional purification processes raw nickel must undergo before it can be used for industrial purposes to isolate pure element.
In contrast, refined nickel which is commonly known as “nickel” has been highly processed to attain purity levels that are usually over 99%. This is the form primarily utilized in making various products like stainless steel, batteries and special alloys. It helps remove impurities together with unwanted materials hence meeting product requirements in terms of quality and performance for many different technological and industrial applications.
In short while raw nickel represents a more initial unpurified state of metal got directly from mining; refined nickel has undergone processing to obtain high degrees of purity necessary use in numerous valuable applications of the same.

Where Does Raw Nickel Come From?
Nickel Mining and Extraction Processes
There are several stages involved in the extraction of nickel which can vary greatly depending on whether the ore is a sulfide or laterite. In the case where laterite ores are concerned, the process generally starts with mining, followed by drying and then reduction using rotary kilns to make nickel pig iron or ferronickel. Then it undergoes refining through methods such as hydrometallurgy that include processes like pressure acid leaching (PAL) or high-pressure acid leach (HPAL) to increase its concentration of nickel.
The process for sulfide ores commences with mining after which there is crushing and grinding aimed at freeing nickel from surrounding material. The resulting pulp is subjected to flotation so as to generate a concentrate of nickel, which will be smelted in a furnace to produce a nickel matte. Further refining of this matte can be done using techniques such as Sherritt-Gordon procedure and electrolytic refining in order to obtain high purity nickel products.
Both ways are energy intensive and require extensive use of chemicals; hence stringent environmental control measures are necessary. Extraction technology advances and more recycling of materials containing nickel have been put in place in order to reduce ecological effects related with production of the metal.
Nickel Deposits and Nickel Ore
It is also claimed that nickel deposits are divided into two major types: sulphide and laterite deposits. Generally, sulphide deposits are located at great depths within the earth’s crust and occur in areas with a historical background of volcanic and tectonic activity such as Canada, Russia and South Africa. These sulphides usually contain nickel combined with sulfur gas while their ores often have more nickel concentration compared to the laterites. Commonly extracted sulphide ores include pentlandite as well as nickeliferous pyrrhotite.
Laterite deposits for instance are found nearer the earth’s surface in tropical and subtropical regions like Indonesia, Philippines, Australia among others. They result from prolonged weathering of ultramafic rocks which makes them rich in nickel and concentrated in soil. The percentage composition of these minerals is generally lower than corresponding percentages in sulphides though they are easier to mine since they occur on the surface than underground. The average grades of these ores vary from garnierite through limonite to saprolites.
These varieties of nickel ore provide global reserves for this metal required by stainless steel production enterprises, battery producers and other industrial applications globally.
Global Nickel Production Rates
The global production of nickel has experienced notable fluctuations due to different market dynamics and geopolitical factors. As per the latest information, Indonesia, Russia and the Philippines are the top global nickel producers.
Indonesia is leading in terms of nickel output majorly attributed to its abundant laterite reserves and favourable mining policies. Recent investments into Indonesian mining sector have increased its capacity to produce by adding around 30% of total world’s nickel output.
Next is Philippines as a second biggest producer which mainly utilizes its vast laterite deposits. Environmental regulations aimed at conserving nature on one hand give rise to occasional temporary shutdowns and changes in output levels from the country’s mines.
Russia follows as the third largest with significant nickel production from sulfide ores especially those found in Norilsk region. Nickel mining enterprises in this country are well-established and technologically advanced thus making it an important contributor to global production.
Together these three countries act as key players in satisfying the worldwide demand for nickel particularly because of stainless steel manufacturing and rapidly expanding electric vehicle battery industry.
What Are the Different Types of Nickel?
Nickel deposits mainly exist as two types: laterite and sulfide.
Laterite Nickel Deposits: They form in tropical or subtropical climates, where ultramafic rocks undergo intense weathering processes with a result of nickel concentration. They usually thrust close to the land surface enabling the easy mining of them through open pits.This kind is prevalent in areas like Indonesia and Philippines. HPAL (High Pressure Acid Leach) or pyrometallurgical methods are commonly used for laterite ores processing.
Sulfide Nickel Deposits: These are found in either ultramafic or mafic igneous rocks that are formed by a process called magma. Being found at greater depths, they require underground mining techniques. Russia, Canada and Australia tops the list of countries hosting significant sulfide nickel depositations. Flotation is normally used for treating sulfide ores to a concentrate which is then smelted and refined into pure nickel.

Pure vs. Alloyed Nickel
Diverse characteristics are exhibited by pure nickel and alloyed nickel, making them ideal for different applications. Pure nickel, which contains a lot of nickel (usually more than 99%) is highly resistant to corrosion; it has good thermal conductivity and mechanical properties. It is extensively employed in environments where resistance to both acids and alkalis are vital such as chemical processing equipment and electronics.
Alloyed Nickel on the other hand, involves addition of other elements such as chromium, iron or copper to enhance specific properties like strength, heat resistance and durability. These are used in numerous industries such as aerospace, marine and power generation because the materials must survive harsh conditions called Inconel or Monel.
In conclusion while pure nickel is chosen due to its superior corrosion resistance as well as purity alloyed nickel is preferred majorly due enhanced mechanical properties & versatility under high-stress environments.
