(PDF) Characterization of Foundry Waste Sand

The local South African foundry industry discharges large volumes of waste sand each year, with estimates for silica and chromite sands of 250,000 and 25,000 tons, respectively.

Foundry waste beneficial to other industries South

The foundry industry is one of the greatest recyclers; however, it generates many waste products that end up in landfills when, in fact, they can be used in several applications, says US Department of Agriculture research soil scientist Robert Dungan. Speaking at the 2013 South African Metal Casting Conference, in the North West, on March 14, he noted that there were solutions for waste, such

The local South African foundry industry discharges large volumes of waste sand each year, with estimates for silica and chromite sands of 250,000 and 25,000 tons, respectively. As a developing country, South Africa is moving toward a greener environment, so the management of industrial waste is an imperative area of study. In this work, we present the laboratory analysis results of the

waste foundry sand, which has been classified as hazardous waste material for landfill under the South Africa Environmental waste Management Regulation Act rather than inert waste as is the case in other country such as Germany and United Kingdom. The classification regarding the SA waste foundry has an

Characterisation of Five Different South African Waste

In South Africa, a large amount of natural sand has been extracted. The sand utilization in 2015 was 1900 Mt and trends suggest an 8 % annual increase in sand usage. To abate the use of natural sand in concrete, the South Africa Waste Management Act 2008 [4] provides an incentive that encourages the use of waste

2020-1-27  • Technologies available for the beneficial use of this waste 2.2 Foundry Sand Foundry sand is a silica sand mixed with chemicals and lubricants and used for the casting and moulding of various metal items. Due to the chemical and metal contaminants, oundry f sand is classified as a hazardous waste in South Africa (NEM:WAA, Act 26 of 2014).

Characterization of South African waste foundry

Waste foundry sands are invariably contaminated to some extent during the manufacturing of cast alloys. As such the sand is regarded as a hazardous material that requires exceptional precautions for its disposal. Therefore, the study is initiated to identify, quantify and to classify metallic contaminants present in these sands.

Beneficial Uses of Spent Foundry Sands Sustainable

2021-1-26  Beneficial Uses for Spent Foundry Sands. EPA's risk assessment for the beneficial uses of spent foundry sands found that that silica-based spent foundry sands produced by iron, steel and aluminum foundries can be safely reused to save energy, reduce the need to mine virgin materials, and reduce costs for both producers and end users. EPA supports the use of silica-based spent foundry sands

Waste foundry sand characteristics CORE

Most foundries in South Africa use sand for moulding purposes. Waste foundry sand represents up to 80% of solid waste generated by metal casting facilities. Hence, the characterisation of those wastes is an important area of investigation to determine the composition, nature and classification of this foundry

Recovery of Silicon Dioxide from Waste Foundry Sand

The high amount of waste foundry sand (WFS) produced in South Africa and the high disposal costs have necessitated the development of a solution to deal with the waste generated. WFS has been the focus of extensive research in recent years. South Africa has been

Waste Foundry Sand Usage for Building Material

In order to bring a solution to the problem of waste foundry sand (WFS) in the foundry sector and achieve its reuse, geopolymer building material (as a cementless technology) was produced from the WFS for the first time in the literature in this study. The physical and mechanical characteristics of this material were determined. In the first part of the experimental step, the sieve analysis

What is Zircon Sand? What is Zircon Sand used for

About Zircon. Zircon, also referred to as zirconium silicate (ZrSiO 4), is a co-product from the mining and processing of ancient heavy mineral sand deposits.Mined mainly in Australia and South Africa, zircon can be used either in its coarse sand form or milled to a fine powder. Its properties ensure that it is used in many everyday products, including ceramic tiles and medical implants, as
