About ACG Paste

This conference brings together academics, designers, practitioners, consultants and suppliers to discuss best practice, improved methods and technology, with an emphasis on safety, efficiency, and environmental impact. The conference themes include:

Thickening and filtration
Rheology
Surface disposal
Transportation
Instrumentation and monitoring of tailings
Underground and backfill

With many operations now retrofitting their plants and tailings storages from conventional to thickened technology, the theme of this conference is very timely for an industry that is increasingly concerned with long-term sustainability.

Minefill Seminar

Backfill has undergone significant evolution over the past century, especially with the advent of cemented paste backfill (CPF) more than three decades ago. CPF has emerged as the most widely adopted form of backfill, offering numerous benefits. These range from its rapid delivery and engineered strength to environmental advantages achieved by placing tailings underground and minimizing the footprint of surface tailings storage facilities.

The seminar will begin by exploring the role of CPF within both mining and tailings cycles. It will then delve into operationally focused topics, covering aspects such as monitoring and documenting a backfill system, adapting systems to operational changes, and examining case studies that illustrate how operations have navigated these adjustments.

Session: Types of backfill and their uses

Time: 10.15AM

Date: 19 April 2024

Presenter: Tony Grice

Join Tony Grice as he presents on the three primary backfill options: rock, hydraulic, and paste fill. He will explore how mines can choose and implement the most suitable option(s) to align with their technical, economic, and ESG (environmental, social, and governance) objectives.

This seminar aims to bring together backfill specialists, leaders, and operators from around the globe to present a comprehensive learning experience.
