SMM manufactures electrolytic copper by refining copper concentrate mainly imported from South American countries in flash furnaces controlled by an online computer in the Toyo Smelter & Refinery, which is refined to 99.99% purity or higher after going through the converter, refining furnace, and electrolytic plant. Since our electrolytic copper is superior in electric conductivity and workability, it can be used for a wide array of applications, from cutting-edge electronics parts to various electric wires, including general purpose wire. Additionally, due to its superior thermal conductivity coupled with superior workability, it is also used for various copper alloy fabricated products, including copper pipes for air conditioners. It is also heavily used for plated alloys aiming for a high-class image of metals.
Quality characteristics
99.99% or higher
Applications
Various electric wires, from general purpose wire to extra-fine wire
Copper alloy fabricated products such as plates, ribbons, and tubes
SMM slag sand (granulated copper slag) is made by crushing slag generated in the copper refining process into a sandy condition using running water. Having iron and silicic acid as its main components, it is a physically stable product of consistent quality.
Applications
Cement raw material (iron supplementation)
Sandblasting (rust scouring of iron surfaces)
Caisson (filling material)
Packaging
Bulk carrier

Slag Powder
Overview
SMM slag powder (iron fine powder) is a product consisting of iron and silicic acid, which remains after cooling down, and crushing converter slag generated during the copper refining process and recovery of copper by means of floatation. It hardens well when it dries and is appropriate as a cement material or construction material.
Applications
Cement raw material
Iron supplementation

Gypsum
Overview
Gypsum is dihydrate gypsum in white powder form. Dihydrate gypsum is produced by adding two molecules of water of crystallization to the composition of calcium sulfate, which is a by-product of copper refining.
Quality characteristics
SO3 (45 to 488%), CaO (31 to 34%), water of crystallization (18% or higher)
Applications
Setting modifier for cement
Raw material for gypsum boards

Thallium
Overview
Thallium has been attracting attention for its usage in optical lenses of copying machines and optical fiber systems, etc., and it is a prime example of a rare metal, extremely small amounts of it being contained in lead and zinc. It is very difficult to extract high-purity thallium; therefore, there are only a few manufacturers of thallium in the world.
SMM produces high-purity thallium through our uniquely developed patenting processes, and it is highly evaluated. We provide various types of salts in addition to metals.
Characteristics
The product is provided in the form of ingot with 99.99% or higher purity.
Thallium nitrate
Type
Metal thallium, thallium salts
Applications
Optical glasses
Mouse poison
