Hydrometallurgical processes include high-pressure acid leach (HPAL) and heap leach, both of which are generally followed by solvent extraction - electrowinning for recovery of nickel. Another hydrometallurgical routes is the Caron process, which consists of roasting followed by ammonia leaching and precipitation as nickel carbonate.

In nickel production, valves are found in conventional nickel processing as well as in autoclave high-pressure acid leaching (HPAL) circuits. In copper production, offers valve solutions for copper concentrates production, smelting and electrolysis as well as …

Process Challenges. Slurried, crushed ore from the mine is conveyed to the processing plant to be pressure leached with sulphuric acid. The Pressure Acid Leaching area receives the slurried feed, heats it to 225°C and mixes it with hot concentrated sulphuric acid inside four titanium-lined autoclaves. Nickel and cobalt are leached into the ...

high pressure acid leaching (HPAL), which is often used for the extraction of nickel from laterite ore bodies but can also be applied in copper and cobalt production. The two major benefits of HPAL are the quickness of the process and high recovery rates compared to conventional leaching methods. In the HPAL process, the ore is crushed and mixed

Other than the hybrid Caron process the only operating hydrometallurgical process for nickel laterites are HPALs. The first commercial HPAL plant started production in 1959 at Moa Bay in Cuba and still continues today and Sherrit a 50% joint venture (JV) partner in Moa is a partner in the construction of the similar Ambatovy project in Madagascar.

This paper will present Commissioning and Operation Status of Taganito HPAL Plant Project in the Philippines. The Project will produce 30,000 Ni-tons and 2600 Co-tons per year as Mixed (Ni/Co) Sulfide for export to Sumitomo Metal Mining Co., Ltd. (SMM) Nickel Refinery in Japan as its raw material.

Nickel laterite HPAL circuits are known for their complexity and have presented a large number of challenges to process engineers worldwide. An attitude commonly encountered by the author is that ...

The tailings from these cells is sent to another flotation cell, to recover the nickel, and the concentrate is combined with the 3% nickel concentrate to produce a 12% nickel concentrate. Most nickel ores have several recoverable metals in them and the process if commonly a multiple stream of metals recovered.

In Block Pomalaa, PT Vale will partner with Sumitomo Metal Mining (SMM) to develop HPAL (High Pressure Acid Leaching) technology for the nickel processing plant. The plant will process the nickel ore and produce MSP, a Mixed Sulphide Precipitate, containing above 45% nickel which meets the government threshold for product export.

Ravensthorpe Nickel Operations is a nickel mine and hydrometallurgical processing plant located 550 kilometres (340 mi) southeast of Perth, and 35 kilometres (22 mi) east of Ravensthorpe, Western Australia at Bandalup Hill.. Ravensthorpe cost BHP Billiton US$2.2 billion to build but led to $3.6 billion in write-downs when it was shut down in January 2009, after less than a year of operation.

Bay plant is now recognized as the predecessor to the modern HPAL process. Since then, the Sherritt ammonia leach process, along with sulphate oxidative leach (licensed by Sherritt to Outokumpu in 1961), and chlorine leach, have been commonly used for refining nickel matte (~70% Ni) after the concentrates

Various hydrometallurgical flow sheets are being used for the recovery of nickel from laterite ores. Most plants use the Caron or HPAL processes, simple block flow diagrams for which are given in Figure 1. The Caron process is primarily considered for limonitic ores to avoid the acid consumption associated with the iron content in the ore. The
