Tech Magnesium Co-Production Technology provides unmatched process flexibility & profitability

The Tech Magnesium 

Co-Production Facility uses the same  proprietary atmospherically tight electric furnace and isothermal condenser design for both the ULTRA CLEAN Aluminothermic & the CLEAN Silicothermic Process Routes.  Changing the raw materials mix enables four distinct Product Lines to be produced on the same Production Line thereby maximizing flexibility and profitability

Calcium aluminate, high purity & commercial purity alumina and crystalline spinel  can be co-produced with high purity Mg using the ULTRA Clean Aluminothermic Process Route

Calcium silica aluminate white slag can be co-produced with high purity Mg using the CLEAN Silicothermic Process Route

  Co-production of Mg Metal together with 

Calcium Aluminate 

is governed by the following chemical reaction

12CaO(s) + 21 MgO(s)  + 14 Al(l) = 21Mg(g) +  12CaO.7Al2O3(l) 

Calcium aluminate based cement applications encompass castable refractory cement, floor screed, and rapid-hardening construction cements and mortars. The advantages of CA include rapid strength development,  and reduced CO2 emissions

  Co-production of Mg Metal together with 

Commercial Purity, or, 

Higher Purity Alumina 

is governed by the following chemical reaction

3MgO(s) + 2Al(l) =3Mg(g) + Al2O3(s)     

  Using high purity MgO and Al metal enables production of higher purity crystalline Al2O3 (99.9% to 99.99%).  High purity alumina applications include refractory, LED lighting, lithium-ion batteries, semiconductors and sapphire scratch resistant glass. Current pricing for HP alumina ranges between US $5,000 to over $30,000 per ton depending on purity

  Co-production of Mg Metal together with  2CaO.SiO2..Al2O3 white slag 

is governed by the following chemical reaction

 2CaO.MgO(s) + Si(l) = 2Mg(g) +  2CaO.SiO2(s)    

Adding Al2O3 results in a fluid white slag capable of reducing Portland in the cement mix by 30-85%. White slag cement demonstrates extended curing time, a slower heat release during hydration, enhanced compressive strength, and lower CO2 emissions during cement production. Additionally, white slag cement mitigates cold joint issues and is particularly well suited for high-strength and large-scale concrete structures

  Co-production of Mg Metal together with  

MgO.Al2O3 spinel 

is governed by the following chemical reaction

  4MgO(s) + 2Al(l) = 3Mg(g) +  MgO.Al2O3(s)    

Spinel applications include refractories for steel-making applications that provide a combination of resistance to slag corrosion and thermal shock together with excellent hot strength
