GreenSand

Overview

SMM's ferronickel is manufactured by processing ore imported from Indonesia and New Caledonia using SMM's advanced technologies. It is used as a raw material of stainless steel. Since stainless steel has a beautiful luster and is superior in acid and heat resistance, it is used for household utensils, such as spoons or forks and automobiles, as well as for construction materials for buildings or houses, or for various industrial fields such as chemistry, food and brewing, etc. Its application range is expected to continue to develop.

Quality characteristics

1. Chemical Properties

Chemcal composition

The main components are silica (SiO2) and magnesia oxide (MgO). Other components are alumina (Al2O3), calcium oxide (CaO), ferrous oxide (FeO), etc. Other minor components are also components that are contained in natural rocks, etc.

Table-1 Analytical value

Components %
Fe 5-10
MgO 28-38
SiO2 46-58
CaO 0.1-0.8
Al2O3 1.5-3.0

Elution characteristics

As a result of a leaching test based on Notification of the Environment Agency No. 46 (Environmental Quality Standards for Soil Contamination) and Notification of the Environment Agency No. 13 (Testing Methods for Metals Contained in Industrial Waste), the leaching of harmuful substances such as heavy metals was below the minimum limit of determination.
