Definitions
- Laterite ores are potentially the world's largest source of nickel and cobalt.
- most deposits of nickel/cobalt laterites contain three major zones based on morphology, mineralogy and chemical composition. These three zones, from the base to the surface, atop weathered parent bedrock materials are the saprolite zone, the transition zone and the limonite zone. There is generally a large variation in total thickness of the laterite deposit, as well as individual zone thickness.
- the less-weathered, coarse, siliceous and higher nickel content saprolites tend to be commercially treated by a pyro metallurgical process involving roasting and electrical smelting techniques to produce ferro nickel.
- the power requirements and high iron to nickel ore ratio for the lower nickel content limonite blends make this processing route too expensive.
- Limonite ores are normally commercially treated by a combination of pyrometallurgical and hydrometallurgical processes, such as the High Pressure Acid Leach (HPAL) process, or the reduction roast - ammonium carbonate leach process.
- HPAL High Pressure Acid Leach
- U.S. Patent 5,571 ,308 describes a process for heap leaching of high magnesium containing laterite ore such as saprolite.
- the patent points out that the fine saprolite exhibits poor permeability, and as a solution to this, pelletisation or agglomeration of the ore is necessary to ensure distribution of the leach solution through the heap.
- One problem hindering the heap leaching of nickel and cobalt containing nickeliferous oxidic ores is the substantial clay or fine-particle component of such ores, particularly ores which contain significant quantity of limonitic type ores.
- the type of clay content is dependent on the parent rock and the physicochemical environment of the clay formation, but most clays have a detrimental effect on the percolation of the leach solution through the ore.
- the mechanism could be described with "Shrinking Core Model” (SCM) with porous solid product (quartz) formation as shown in the photo of Figure 1.
- SCM Stress Core Model
- quartz porous solid product
- the formation of acid-resistant quartz can act as a "backbone" within the agglomerated pellets and can strengthen and stabilize a heap that includes limonite. Consequently, the inventors have found that a heap charged with lateritic ore may be stable during acidic leach if the ratio of saprolite/limonite type ores is appropriately selected. In one embodiment, the inventors have found that a stable heap may be maintained if the limonite/saprolite blended heap includes 15%-85% wt of limonitic type ore and 15%-85% wt of saprolitic type ore.
- the heap is subjected to a leach process by contacting a heap of the ore with a mineral acid selected from the group consisting of hydrochloric acid, sulfuric acid and/or nitric acid at an acid concentration sufficient to effect the dissolution of nickel, for example, at least about 0.1 molar (equals to 10 g/L H 2 SO 4 ).
- a mineral acid selected from the group consisting of hydrochloric acid, sulfuric acid and/or nitric acid
- sulfuric acid is used.
- the aqueous leach solution may be acid supplemented fresh water, seawater or saline water.
- the leaching is preferably carried out at a temperature of at least ambient temperature and ranging up to about 80 °C, if additional exothermic reaction such as bio-oxidation is introduced.
- the reaction time should be sufficient to dissolve substantial amounts of nickel and some iron and magnesium to provide a pregnant solution thereof.
- the limonite ore generally consists of goethite and/or hematite type particles and is particularly fine and dissolved with acid as shown in Eq. 1 and 2.
- the saprolite ore is coarse silicates which volume was found unchanged during leach as shown in Eq.3 and the photo ( Figure 1 ). Accordingly there needs to be a certain quantity of saprolitic type ore within the heap in order to give the heap some structure backbone during the leaching phase.
- the intermediate pregnant leachate solution may be divided into two fractions with the fraction having a pH of greater than 2 being removed and transferred downstream for nickel and/or cobalt recovery.
- the acidic fraction with a pH of less than 2 may be used for the leach solution in the counter current system.
- the nickel and cobalt rich heap leachate may be divided in a similar manner with the fraction having a pH greater than 2 being transferred for nickel and cobalt recovery, while the acidic heap leachate with a pH of less than 2 is used to leach a fresh heap in the counter current process.
- Figure 2 shows progressive nickel extraction graphs of blended ores
