calviva produtoQuicklime

Calcium oxide is an alkaline product commonly known as lime or quicklime. It is obtained by calcinating calcium carbonate at high temperatures.

CaCO3 + Calor → CaO + CO2

Microlime offers top quality calcium oxides in different fractions, from granulated oxides to micronized oxides.

Through our I + D department of our group special products are developed for different applications and solutions.

USES AND BENEFITS

Steel Industry: used as flux, desulfuriser, and slagging.

Metallurgy Industry: in the manufacture of copper, zinc, lead, silver… Lime is used in the melting, concentration, and refining processes for the above metals.

Paper and PPC Industry: used mainly for causticizing, for recuperation of sodium hydroxide allowing for the reuse of CaCO3 from the process of pulp manufacture. In PPC it is used as a charge and pigment for top quality paper.

Agriculture: acts as a regulator for pH, precipitator for impurities and neutraliser.

Mining Industry: is used for flotation, leaching and cyanidation of metals such as gold and silver.

Construction: for soil stabilization.

Environmental protection: for treating contaminated land, prevent bad odours, and decontamination of water both industrial and urban, as well as treating toxic and dangerous waste.

Sugar industry: for clarification and alkalising of the sugar cane juice. It increases the pH and agglomerates several impurities.

PRESENTATION

• In bulk by tipper truck or powder tanker.
• In Big bags of 600kg, 1000kg, 1200kg, and 1500kg.

caldolomitica produtosDolomitic Lime

Dolomitic lime is obtained by calcinating (burning) the dolomite, with a high degree of calcium carbonate and magnesium CaMg(CO3)2.

CaMg(CO3)2 + calor → CaO MgO

Once the product is obtained, it is classified into several grain sizes, adapting ourselves to the requirements of each sector at which it is aimed.

USES AND BENEFITS

• Steel Industry: it acts as a purifier for different steels and as a protector for refractory coatings.

• Refractories: it is used as raw material for the manufacture of refractory bricks and for increasing the useful life of the refractory coatings in ovens.

• Glass: is used in the manufacture of flat glass to improve stability, diminish de-vitrification, increase the viscosity of glass, it increases the resistance to temperature change and allows reducing the quantity of Silica and fluxes.

• Agriculture: it is used as a corrector to neutralize acidity in the soil, to prepare the soil so that the crop assimilates nutrients, among other uses.

calhidratada produtosHydrated Lime

Calcium Hydroxide is a product that is obtained from the reaction of calcium oxide in contact with water. This reaction is known as hydration or slaked quick lime and is also known as dead lime and/or slaked lime.

CaO + H2O → Ca(OH)2 + calor

Thanks to certain modern and sophisticated manufacturing processes, Microlime can offer products of the very highest quality.

Through our I + D department of our group special products are developed for different applications and solutions.

USES AND BENEFITS

• Environment: for water and sludge treatment and improvement, it disinfects, acts as a regulator for pH, for treating municipal waste, rust stabilisation and control, disinfectants for sewage and organic waste, re-mineralise water that is too soft, among others.

• Metal and Steel Industries: it acts as a regulator for the pH of water used in electrolytic processes for obtaining metals and as a neutraliser and corrector of acid water, used in the pickling and cleaning processes of metal surfaces.

• Mining Industry: the product acts as a regulator of the pH of the water generated in the process, prior to draining to a river, allowing at the same time the separation of metals contained in those waters for reusing. Also used in effluent and waste treatment, as well as the settling, drying, filtration, environmental protection, and safety in mines.

• Construction: for stabilising land by improving stability and impermeability by increasing its density, for mortars offering increased plasticity and workability as well as increasing resistance and with low retraction properties. It can also be used as an additive for the manufacture of asphalt as an anti-separation agent reinforcing the links in the interior of the structure and reducing sensitivity to humidity.

• Agriculture: as a regulator of pH in the soil, vegetable nutrients, fertiliser, fungicide, and steriliser, among others.

• Sugar Industry: for clarifying the product by acting as a regulator of the pH and precipitating impurities. It improves filtration and removes small particles and fibres.

Non plastic material of continuous granulometry, between 0-30mm, in a material called natural or artificial, based on whether it is submitted to a process of crushing or not. Free of any elements that might condition durability, it responds to high resistance to fragmentation.

USES AND BENEFITS

• Bases and sub-bases for roadworks.
• Filler for ditches, sidewalks, and levelling.
• Walls and fillings for staircases.
• Forest paths and rural roads.
