Garnet sand &copper slag: Comparison of environmental impact&cost

1. Detailed Description of Abrasive Characteristics

garnet sand: Natural and Highly Efficient "Industrial Jade"

Environmental Features:

Naturally Pure: Garnet is a naturally formed silicate mineral, free of heavy metals and free silica, making it highly safe and healthy for operators.

Ultra-Low Dust: Its extremely high physical toughness prevents breakage during sandblasting impact, ensuring high visibility in the working environment and minimal secondary dust pollution.

Sustainable Recycling: It possesses excellent recyclability, typically recyclable 3-5 times, significantly reducing waste generation and meeting ESG green production standards.

Cost and Efficiency Features:

Precise Cutting: The sharp particles and moderate hardness (Mohs hardness 7.5-8.0) quickly achieve the desired surface roughness (anchor point), making it particularly suitable for precision marine equipment and high-value metal surface treatment.

Low Consumption: Due to its high recycle rate, the actual material consumption for sandblasting operations of the same area is only 25%-30% of that for a single abrasive application, greatly alleviating cross-border logistics pressure.

Copper Slag: A Powerful and Economical "Heavy Industrial Weapon"

Environmental Characteristics:

Waste Recycling: As a byproduct of copper smelting, copper slag achieves resource recovery from industrial solid waste through abrasive applications, reducing over-exploitation of mineral resources.

Chemical Stability: High-quality copper slag undergoes high-temperature quenching, resulting in a stable internal structure. Heavy metals are mostly encapsulated, exhibiting good chemical inertness in dry environments.

Cost and Efficiency Characteristics:

Outstanding Unit Price Advantage: Its highly attractive unit price makes it the preferred abrasive for "single-use sandblasting and non-recyclable" projects such as large-scale ship rust removal and bridge construction.

High Explosive Power: Due to its high density and sharp edges, it can quickly break down thick layers of rust and old paint, performing exceptionally well in heavy industrial scenarios requiring large-scale, high-intensity stripping.

Wide Applicability:For projects like the Sandblast in the world which require massive consumption, are environmentally sensitive, and are difficult to recycle, copper slag offers an excellent cost-performance balance.
