Business Operation

The Company and subsidiaries produce and supply the main product consist of lime and Calcium Carbonate including produce and install the Marble Products for both domestic and overseas customers. Including the business to distribute trading products and the business in the Engineering design and distribution of the Machine part and Equipment Categories as follows:

1. Lime Product

which consists of calcium oxide, calcium magnesium oxide, and calcium hydroxide

• Calcium Oxide is obtained by burning limestone, a sedimentary rock that consists mostly of calcium carbonate (CaCO3), to a high temperature when the carbon dioxide (CO2) gas is released. This burning process is called calcination. Our lime production burns limestone at 900? Celsius for 18 hours in a closed system, obtaining 1.5 to 4-inch white lumps consisting of 85% or more CaO and some magnesium oxide (MgO) and ferric oxide (Fe2O3). Being alkaline (pH 12.2), they react violently with water releasing a large amount of heat. At the end of the reaction, only a few small cores are left.
• Calcium Magnesium Oxide (CaO MgO) / Dolomitic lime / Burnt Dolomite or / Dolime Calcium Magnesium Oxide or Dolime is a product based on Dolomite stone, which is similar to Limestone or Dolomitic Limestone, but contains a fix ratio of Mg and Ca in the form of CaMg(CO3)2 , has a dense structure, non-crystalline and is available various colors mostly in white and grey,
  
  has a dense structure, non-crystalline and is available various colors mostly in white and grey, Dolime is calcined at temperatures somewhat lower than limestone. During the calcination Carbon Dioxide (CO2) gas is released and first MgO and later CaO are formed. Dolime contains MgO minimum 32% and up to 38%, and CaO minimum 55% up to 62%.
  
  Dolime finds it use in the steel idustry, acting as a flux agent alongside with quicklime. The CaO content of the Dolime will act similarly to quicklime, but the MgO part’s use us to saturate the EAF bath with Magnesium, so that the dissolution of the Mg from the refractory wall of the EAF is minimized, resulting in a greatly prolonged ( 5x up to 10x ) refractory lifetime, reduced downtime, and overall very significant operational cost savings for the steel plant.
• Calcium Hydroxide (Ca(OH)2) or Hydrated Lime Calcium hydroxide or hydrated lime are products of a chemical reaction between ground CaO and water. They are produced in a mixture tank, ground into powder (170-230 mesh), then put into packages or transferred to bulk trucks, and delivered to customers branded as ‘Rhinoceros’.

2. Calcium Carbonate (CaCO3)

Calcium Carbonate produced by grinding Calcite (sand size) into powder. Calcite is also the most stable among the rock-forming minerals with CaCO3 structure. It is glassy luster, transparent to translucent, white or colorless.

3. Marble Products, By-Products from Marble Production, Handicraft and Installation Services

Marble Products, By-Products from Marble Production, Handicraft and Installation Services

Prefabricated marbles Prefabricated marbles are the products derived from the marble quarry operation of TMC or imported from aboard that has been passed through the special until achieving the desired size categorized.

4. Trading products

The Company has imported some products for trading both domestically and export. The trading products consists of the main products such as lime and Calcium Carbonate, other products and petcoke trading (as currently uses) to domestic customers including trading with subsidiary when the customer's demand is higher than its production capacity. Products and by-products from the lime quarry production distributed by TMC.

5. Sales and installation of machinery and equipment

The Sales and installation of machinery and equipment related to the lime production consist of EOD kiln installation, lime and limestone transport and fuel-burning system, including consulting to supply machines and equipment for lime production. The Company has set up a subsidiary company named Golden Lime Engineering Company Limited (“GLE”) and shares 99.99%. The capital registered and paid-up total of THB 20 million to expand the engineering business and equipment supply. The said engineering business was developed to increase the potential and opportunity in the competition and enhance opportunities in consulting lime production in the future.
