Aluminum Dross (Black)

Description

1. Product Overview

Aluminum Dross (Black) is a secondary aluminum by-product generated during the aluminum melting and refining process, characterized by lower metallic aluminum content and higher oxide and salt fractions compared to white dross. It is primarily utilized in aluminum recovery operations, salt slag processing, and as a raw material for industrial mineral applications. The key value proposition lies in its recoverable aluminum units and its suitability for downstream material extraction, offering cost-efficient feedstock for recyclers and processors. In a resource-constrained and energy-intensive global aluminum market, Black Aluminum Dross plays a strategic role in maximizing metal recovery, minimizing waste, and supporting circular production systems.
