Copper : Copper: Red-brick Metal, Ductile With Electrical And High Thermal Conductivity. Obtaining: - Generally From Sulphurous Concentrates, By Melting For Matt, Followed By Concreting And Obtaining Blister Copper (about 97.5% Cu). After Thermal Refining Of The Converter Copper, Thermal Refined Copper (about 99% Cu) Is Obtained, Followed By Final Purification By Electrolysis Up To Min. 99.95% Cu Use : - In Particular In The Form Of Electric Conductors For The Transport Of Electric Power Or In Windings For Electric Motors. A Large Share Of Copper Consumption Is The Manufacture Of Various Brands Of Alloys (brass, Bronze). - In Civil And Industrial Constructions, They Are Mainly Used As Pipes For Installations Or Roof Tables. Properties : - Red-brick Metal, Ductile With Electrical And High Thermal Conductivity. Material Specification : Stas 201 / 1-80. Brand : Copper Cathodes With 99.99k; With 99.97k, Cu 99.95k Form Of Presentation : Cathodes
Zinc : Zinc: White-white Metal, Brittle, Cold-deformable But Possible To Be Laminated Between 100 - 150oc. Obtaining : - From Complex Concentrates (pb - Zn) By Oxidative Frying, Followed By A Reduction In Furnace (isp Process). - The Crude Zinc Obtained In The Blast Furnace Is Subsequently Purified Either By Fractional Distillation (new Jersey Process) Or By Electrolytic Refining. - By Hydrometallurgical Way, When The Fried Concentrate Is Subjected To Solubilization With Znso4 Formation. After Purification, The Solution Is Subjected To Electrolysis, A Process Resulting In A Zinc With A Purity Of Min. 99.99% Zn. Use : -coating Of Steel Sheets And Foils For Corrosion Protection; -obtaining Of Copper-based Alloys, Resistant To Corrosion (brass, Alpaca) - Obtaining Of Castings Under Pressure From Zinc-based Alloys (zamac) Etc. -obtaining Zinc Oxide With Uses In The Pigment Factory, Rubber Industry, Medicine, Ceramics, Etc. Properties: - White-blue, Brittle, Cold-deformable But Possible Laminate Between 100 - 150oc.

Presentation Form : Ingots Provenience : Import From Poland, Bulgaria Etc
Hi, I am from Romania, I am a farmer and we produce natural organic honey. We want to sell our honey. We can send you video and picture with our bees farm. In our village we are more farmers that want to sell our honey. Everything is narural, we donot use any medicine or chemicals supplements. I am also engineer in environmental protection. I hope you will contact me for future updates! Thank you!
