Bulk Pulverized Quicklime for pH Control in Gold/Copper Mining - High Reactivity Calcined Lime
Product Description: High Performance Quicklime for Mining & Metallurgy
Product Overview
Boost your extraction efficiency and steel quality with our premium Industrial Grade Quicklime Powder. Also known as Calcium Oxide (CaO), Burnt Lime, or Unslaked Lime, our product is precision-calcined to ensure High Reactivity and minimal impurities. It is the ideal chemical reagent specifically engineered for the rigorous demands of the Metallurgical and Mining industries.
Why Choose Our Quicklime?
-
Superior Purity: With a CaO content of 95% to 97%, our quicklime ensures maximum efficiency with less material usage.
-
High Reactivity (T60): Reacts rapidly in processes, significantly reducing processing time in steel converters and flotation tanks.
-
Low Impurities: Strictly controlled levels of Sulphur, Silica, and Magnesium prevent contamination in your final metal products.
Applications in Mining & Metallurgy
1. Steelmaking & Metallurgy (Fluxing Agent)
Our Metallurgical Grade Quicklime acts as a superior fluxing agent in Basic Oxygen Furnaces (BOF) and Electric Arc Furnaces (EAF).
-
Desulfurization: Effectively removes Sulphur and Phosphorus from molten iron and steel.
-
Slag Formation: Promotes early slag formation to protect refractory linings and improve steel purity.
