Nickel is a metal with a silver-white luster. It can be forged and forged welding like iron, and is rich in malleability and ductility, and  can be polished. It has strong magnetism but weaker than iron. Thermal and electrical conductivity is low. Electrical conductivity is  14.9% of copper. It is more stable than iron in air and moisture and is not oxidized well and does not corrode well with alkali. Dilute  nitric acid is readily soluble but dense nitric acid is immobile as iron, and is not eroded. React violently with chlorine and bromine.

Nickel is used in a wide variety of applications in addition to its proven superiority in stainless steel. Especially, due to its beautiful luster and corrosion resistance, it has been treated as the best alloy element in the special alloy field  and it is expected to remain the total metal industry in the future.

PT KUNZ PRIMERA PRATAMA (KPP) plant to processing of Nickel Plant based on the Monolith’s Innovation  Technology “MACH” (Monolith Advanced Clean Hydrometallurgy) to produce High-Value Products including Nickel, MgO, Fe-Si, and etc. With “MACH” technology, we have High Value Products Manufacturing, Extremely Eco-friendly Tech, No Slag, No Waste, No Liquid Discharge, No Direct Handling of Hydrochloric Acid, Not using High Pressure, etc. Profitability Seller’s Market makes Stable Revenue, Big Sale and Low Cost makes Excellent Profitability. Nickel ores fully converted to commercial goods 2 times more sales than other plants. Construction of the project was conducted by Company in cooperation with Monolith Company to jointly form a new company PT KUMAMO POWER ENERGI.

Historically Nickel production has been based on Nickel Sulphide and High-grade Saprolitic Laterites using Smelting process. However, Future production will have to come from Low-grade Laterites and Smelting process will be Un-Economic. Hydrometallurgical Processes using Acid Leaching are the Alternatives, but it’s a not something new. High Pressure Acid Leaching (HPAL or PAL) is Already Commercialized but Atmospheric Acid Leaching (AL) using HCl is Not still  Commercialized. HPAL Process is doubtful whether can be Economic because of High CAPEX, operating Difficulties and the High Acid Consumption. Although AL process have several advantage, but it is Not commercialized because of Difficulties of Pyrolysis and HCl Recovery. Monolith’s “MACH” process takes Advantage of the Atmospheric Acid Leaching Process. And, “MACH” process solved the AL process issue using “Gel Breaker” and its own (Self-developed) Pyro-System with “Ceramic Filter”  and “Direct Leaching System by HCl Gas”.


Nickel is secondary Battery Industry’s Key Ingredient and Indonesia is the best location to produce high quality nickel and cobalt. The Biggest Nickel Belt in Indonesia, a lot of nickel mines located including our Exclusive Mining Site in Southeast Sulawesi. KPP Securing All Important Licenses and Monolith Securing Innovation Patent Technology “MACH” for Plant.

Indonesian Government has started supporting “Low-cost, High-efficiency & Environmentally friendly” Technology for Indonesian people. Conventional Smelter methods extract nickel only and remove all remaining to waste, the existing high-pressure system such as HPAL (High Pressure Acid Leaching)  damages environment and also hold risk of explosions. We use “MACH” Extremely Eco-friendly Tech, No Slag, No Waste, No Liquid Discharge, No Direct Handling of Hydrochloric Acid, Not using High Pressure, etc. 

The production of magnesium oxide and  silica, which other smelting facilities cannot  extract, resulted in significantly higher sales than existing plants. Producing & Sales on High Value Products  as Nickel, MgO, SiO2, and etc. “CAPEX” and “OPEX” is much lower than other smelting facilities. No Waste (Fully converted to commercial goods) so lowest cost of  raw material (nickel ore). Significantly lower CAPEX due to no need for high temperature and high pressure with breakthrough technology, significantly lower OPEX due to lowest raw material cost and no need for high temperature and high pressure. Nickel ores fully converted to commercial goods 2 times more sales than other plants.
