“…Serpentinite has no significant effect on the yield of perennial grasses, but significantly increase the magnesium concentration in the grass dry matter, which reduces the risk of hypomagnesaemia in cattle. It has been found that serpentinite can substitute more soluble magnesium fertilizer (Chittenden et al, 1967;Haynly et al, 2005). The research carried out in Lithuania showed that granular serpentinite significantly increased the total, marketable seed and fodder potato tubers yields of one shrub .…”

The influence of processing the serpentinite quarry from the Caucasian mountains at the foot of the Mount Elbrus crushed waste on soil agrochemical properties, phytotoxicity of spring barley, influence on barley plant biomass and its chemical composition were investigated. Ground and granular serpentinite had a different effect on soil and plants. Application of serpentinite fertilizers significantly increased the content of calcium, iron, 227.95-376.75 and 5.05-9.62 mg kg-1, total and plant-derived magnesium 0.34-0.52 and 1.19-2.16 mg kg-1, lead and nickel, while the amount of copper dropped substantially; the soil was becoming more alkaline. Application of ground serpentinite lead to alkalizing of the soil much more compared to the granular, with a significant increase in plant-derived magnesium. The influence of serpentinite increased the yield of spring barley plants in green and dry mass by 0.049-0.256 and 0.011-0.046 g or 0.65-3.41 and 1.19-2.59% out of the growing vessel, and dry matter increased by 0.12-0.26 % units, the yield of spring barley green and dry mass under the influence of ground serpentinite was higher than of granular serpentinite fertilizer, and the dry matter was found to be significantly higher than that of unfertilized spring barley plants. Ground and granular serpentinite was not phytotoxic to spring barley. An application of ground serpentinite increased an amount of calcium, potassium and magnesium in the barley dry matter compared to the granular serpentinite. Ground and granular serpentinite reduced the amount of trace elements copper and manganese in the dry mass of the plant, and the amount of zinc decreased only after fertilization with granular serpentinite. An application of serpentinite significantly decreased content of lead, chrome and cadmium while nickel content significantly increased in the dry matter of barley plants.

“…10 Indeed, due to the basicity, serpentinite has been used as a Mg source and replacement of lime. 11 In addition, due to the thermal properties of serpentinite it is also used as flux agent to produce thermal-phosphate fertilizers. 12 Previous studies have shown that alkaline metals, such as Li + , Na + and K + can be intercalated in the serpentinite structure and upon thermal treatment form different Mg silicates such as Li 4 SiO 4 /MgO, 13 Therefore, the K 2 MgSiO 4 phase produced from the available and low-cost serpentinite can be a source of K or Mg in slower release rates compared with traditional soluble sources, which could be highly advantageous as potential fertilizers.…”

In this work, a potassium magnesium silicate mineral based on phase K 2 MgSiO 4 was prepared from serpentinite rock and studied as a potential K and Mg slow-release fertilizer. The material was prepared by impregnation of serpentinite/KOH and calcination at 700 °C to produce K 2 MgSiO 4 phase, olivine and forsterite. The release patterns of K and Mg in the stirred-flow trial and leaching through the soil columns showed that K 2 MgSiO 4-based materials released K on lower rates than KCl and MgSO 4 .7H 2 O, however, there was no evidence of Mg release. The extraction with 1 mol L-1 NH 4 OAc showed a considerable content of Mg and K for K 2 MgSiO 4-based materials, due to exchange of NH 4 + and Mg 2+. X-ray diffraction (XRD) analysis of materials impregnated with K and calcined showed peaks relative to K 2 MgSiO 4. After leaching, the peaks intensity diminished, supporting that part of K leached. Therefore, the samples showed great potential as slow-release K-fertilizers when compared with KCl source.

“…O serpentinito é uma rocha que possui aplicações em diversos seguimentos, é utilizada como rocha ornamental [1], fertilizante fonte de MgO na agricultura [2], fonte de MgO no processo siderúrgico [3] e agente anticlustering nas pelotas utilizadas no processo de produção de ferro metálico através de redução direta [4]. Nos dois últimos exemplos o serpentinito passa por processo térmico durante sua utilização e com isso tem sua estrutura cristalina redefinida Tecnol Realizou-se também análise termogravimétrica em atmosfera inerte (N 2 ), de acordo com os parâmetros abaixo:…”

Este trabalho caracterizou uma amostra de serpentinito in natura e após calcinação em forno mufla a 1200ºC. Foram utilizadas as técnicas analíticas: análise química, difratometria de raios-X (DRX), microestruturas por MEV e EDS. A DRX confirmou os minerais filossilicatos, lizardita e talco, como os principais constituintes desta amostra, e a magnetita em menor quantidade. Foi feita termogravimetria (TG e DTG) até 1450ºC e os resultados mostraram uma perda de massa total de 12,15%, além de dois picos: da lizardita a 645ºC e do talco a 729ºC. Para analisar as fases ricas em ferro, utilizou-se a espectroscopia Mössbauer, com espectros registrados à temperatura ambiente. Além disso, a amostra calcinada foi também analisada na temperatura muito baixa de 25K. Estes resultados completaram a composição de fases, com a diminuição da quantidade de magnetita e a presença significativa de magnesioferrita. As fases dominantes foram forsterita e enstatita, ambas contendo ferro na composição. Pela análise microestrutural, observou-se a mudança morfológica das partículas, com diminuição expressiva das fibras finas, para formas mais arredondadas de bastonetes indicando o início do processo de sinterização.
