UM - Antimony Concentrates

OVERVIEW

Antimony concentrates, primarily sourced from Stibnite (Sb₂S₃), are vital components in various industrial applications, including flame retardants, battery manufacturing, and alloy production. At United Metals, we integrate advanced beneficiation techniques with comprehensive geological survey data to enhance efficiency, optimize recovery rates, and ensure sustainable production methods for high-quality Antimony concentrates.

OUR EXPERTISE

We specialize in processing Antimony sulphide ore with an average grade of 25% Sb and refining it into high-grade antimony concentrate with a consistent antimony content of 45%. Our advanced beneficiation techniques ensure maximum recovery and purity, making our product highly sought-after in international markets.

UNDERSTANDING ANTIMONY AND ITS INDUSTRIAL SIGNIFICANCE

Antimony is increasingly recognized for its critical role in modern manufacturing processes. The rising demand for Antimony in sectors such as electronics and automotive underscores the need for efficient beneficiation processes that maximize yield and purity from ore deposits.

Identify Key Deposits: Understanding the distribution and grade of Stibnite and associated minerals.

Assess Mineralogy: Recognizing the presence of secondary minerals like Valentinite (Sb₂O₃) and Senarmontite (Sb₂O₃), which contribute to overall Antimony content.

This geological insight is crucial for optimizing the beneficiation process and ensuring efficient extraction of valuable resources.

Stibnite (Sb₂S₃) - Primary antimony sulfide mineral
Valentinite (Sb₂O₃) - Natural antimony oxide
Senarmontite (Sb₂O₃) - Cubic crystal form

BENEFICIATION PROCESS OVERVIEW

The beneficiation of Antimony concentrates involves a series of well-defined stages, utilizing state-of-the-art techniques informed by geological survey data to extract maximum value from Stibnite ore.

Mining and Material Handling: Efficient mining practices are foundational to successful beneficiation. We employ selective mining techniques based on geological survey data to target high-grade Stibnite deposits, ensuring optimal resource utilization while minimizing waste. Safety protocols are strictly followed to protect our workforce and the environment.
Crushing and Grinding: The first stage in the physical separation of Antimony minerals involves crushing and grinding the ore to liberate Stibnite from gangue materials.
Flotation: Flotation is the primary method for separating Antimony minerals from other constituents. Our approach includes: Reagent Optimization & Air Flow Management.
Concentrate Thickening and Filtering: Post-flotation, the Antimony concentrates undergo thickening and filtering processes.
Quality Control and Assurance: Quality control is integral to our beneficiation process. We employ rigorous testing protocols to ensure our Antimony concentrates meet industry standards.
Sustainable Processing Methods: At United Metals, sustainability is at the core of our operations. We are committed to minimizing our environmental footprint through: Waste Management Practices & Community Engagement.

PARTNER WITH US

At United Metals, we are committed to building long-term partnerships with clients worldwide. Whether you are looking for a reliable supplier of high-quality copper concentrate or exploring opportunities in the mining sector, we are here to collaborate with you.

SUPPLY CHAIN ACTIVITIES:

Procurement:

We now source Antimony ore from Zimbabwe, and we are expanding our sources to Mexico. These products are offered mainly on long term basis. We promise our international customers a maximum level of continuity in the supply of affordably priced Antimony ore.

Each month, we are able to deliver up to 1,000 MT of Antimony concentrates. We will eventually be able to increase supplies to 2,000 MT per month by broadening the seller portfolio.

Transportation:

In order to ensure that the items are delivered from the mine or production facility to the loading port in a safe, effective, and timely way, the transport department is essential to the export process. Loading and unloading, transportation, documentation and communication, safety and compliance are some of the actions involved in this operation.

The Road & Rails network efficiently connects our production facilities to loading ports and secure storage facilities.

Logistics:

To ensure that the items are carried from the mine or manufacturing facility to the loading port safely, effectively, and by all applicable regulations and requirements, the logistics department is essential. To guarantee that the entire export process goes smoothly and that the items arrive at their destination on schedule and in good shape, we work closely with the production, customs, and transport departments.

The logistics department is essential to the export process because it makes sure that the commodities are efficiently and affordably transported from the mine or production facility to the loading port. We offer the greatest services in terms of goods forwarding, shipping documents, transportation administration, and cargo insurance.

We provide international containerized and bulk transportation services on ExW, FCA, FOB, and CIF terms.

Pre-shipment inspection (PSI):

Pre-shipment activities at the loading port are critical to ensuring that all laws and regulations export the goods, reach their destination on time, and are in good condition.

We collaborate with international pre-shipment organizations such as CCIC, Alex Stewart, Intertek, SGS, Mitrask, etc.

Pre-shipment tasks that frequently occur at the loading port include packing and labeling, inspection and quality control, customs clearance, loading and stowing, and creating and submitting the necessary documentation for the shipment, such as bills of lading, packing lists, and commercial invoices.
