Below from QRR on adfvn, any thoughts?
Hmmm interesting bit, wonder if it would benefit Amur Minerals JV etc and below project begun after Russian and China signed all documents last year......who is participating in this project????

Welcome to the Sino-Russian Science and Technology Cooperation Information Network!
Development of water metallurgy technology for extracting nickel and cobalt from laterite iron ore
Overview: The project aims to develop an ecological safety technology for extracting nickel and cobalt with a yield of not less than 90.99%. When using this technology, the pure metal production is increased by 0.5 times and the material flow is reduced by 1/2.
Full description: The project aims to obtain ferronickel raw materials for non-ferrous metal smelting and ferrous metal smelting, in which the nickel content is 9-18%. The technology includes ore, coal and flux additives to prepare the charge, in the rotary tube furnace to reduce the roasting of the ore, the hot melt block is discharged into the water from the furnace, the cooling frit is ground and separated, and the nickel iron is precipitated. Particles. The ore is subjected to reduction roasting in a two-stage apparatus. The device consists of two rotary furnaces connected to each other by a thermal chamber. The iron and nickel in the ore are reduced in the first rotary furnace, the material is melted in the second rotary furnace, the metal particles are combined, and nickel iron particles are formed in the range of 1300-1350 °C. The nickel extraction rate in the ore is 90-96%. The slag is environmentally friendly and can be used as construction materials for construction. This technology allows the use of saprolite ore with an iron (Fe) content of 12-25%. Compared with the existing process, the design technology does not form slag, reduces the reduction roasting process time by 1/2, and reduces the fuel consumption, that is, the performance of the furnace is doubled. Therefore, the whole process technology Economic indicators have all improved. At the same time, the extraction cost of nickel is 1/2-1/1.5 of the cost of the world's competitors.
Form of cooperation: carry out scientific research and experimental design work, establish joint ventures
