There are 7 kinds of materials mainly S230403 stainless steel, with thicknesses of 4-22mm. We use the LINSINGER fully automatic edge milling machine whose working efficiency is ten times more than ordinary machines. This batch of prefabricating steel tank plates has gone through the processing of cutting, edge planing, roll forming, pressing, pre-packing, etc. This order fully demonstrates our advantage of a one-stop service in metal materials and metal fabrication.
The prefabricated plates are mainly used for the smelting of laterite ore.
Primary nickel is produced from two very different ores, lateritic and sulfidic. Lateritic ores are normally found in tropical climates where weathering, with time, extracts and deposits the ore in layers at varying depths below the surface. Lateritic ores are excavated using large earth-moving equipment and are screened to remove boulders. Sulfidic ores, often found in conjunction with copper-bearing ores, are mined from underground. Following is a description of the processing steps used for the two types of ores.
Sulfides have long supplied the bulk of the global appetite for nickel. But dwindling resources combined with the need to mine at greater (and subsequently less economic) depths to obtain sulfide ores has many miners looking at nickel laterites. Additionally, nickel is expected to see growth in demand as developing economies spur a greater need for stainless steel. Similarly, demand is expected to grow as a result of nickel’s use in lithium-ion batteries; nickel is used in the cathodes of lithium-ion batteries and although this is not a new application (lithium-ion batteries have already seen widespread use in consumer electronics), the lithium-ion battery market is expected to see substantial growth as a result of the electric vehicle trend. On top of that, the amount of nickel used in such batteries has been increasing in an effort to improve performance. As such, the world is looking ahead at what can be done to maintain (and likely increase) a reliable and economic nickel supply.
Nickeliferous laterite ores are abundant, with experts estimating that they account for about 70% of known global nickel resources. They are also close to the surface, unlike sulfide deposits, which are mined at much greater depths. This abundance and ease of accessibility makes laterite ores an attractive option to the nickel industry.
The downside to laterite ores, and the reason why they haven’t been exploited on a widespread scale thus far, is that they require much more energy in processing over sulfide ore types.
While sulfide nickel ores are processed via upgrading to concentrates and then smelting, this approach is not applicable to laterite ores. A variety of approaches are available to process nickel laterite ores, with the most prevalent approaches explained below.
The method(s) chosen is dependent on the composition of the unique ore source. Most laterite ore deposits are made up of both limonite (iron rich) and saprolite layers, with the thickness of each layer varying significantly across different deposits.
Limonite, which accounts for nearly double the amount of saprolite available globally, is more amenable to processing via hydometallurgical techniques, while saprolites are more amenable to processing via pyrometallurgy.
As a critical component in stainless steel and lithium-ion batteries, the waning nickel sulfide resources have many looking at nickeliferous laterite deposits as the future of the industry. Both hydrometallurgical and pyrometallurgical approaches are utilized to process nickel laterite ores, with the best approach depending on the ore composition.
