Vietnam government encourages use of slag in cement production

17 May 2021

Vietnam: The government has encouraged cement producers to increase their uptake of waste products, including slag, in cement production. The Viet Nam News newspaper has reported that the government has asked the Ministry of Construction and related agencies to complete the formulation of technical standards, regulations and instructions in relation to the use of slag as well as researching new applications for it. The Ministry of Industry and Trade has also started inspecting storage sites to ensure that it doesn’t exceed two years worth of production. The government initiative has been made in response to rising stockpiles of slag, ash and gypsum.

BMR Group competes ISF Slag tests

03 October 2016

Zambia: BMR Group has finished laboratory scale test work on its imperial smelting furnace (ISF) slag dump at its Kabwe site. The company now intends to commission a study to convert its ISFS stockpile into a Joint Ore Reserves Committee (JORC) compliant resource. The site contains potentially 120,000t of zinc.

"These results are especially encouraging as they demonstrate the potential for BMR to extract a greater proportion of the in situ materials at Kabwe than previously anticipated for the benefit of our shareholders. We will therefore be commissioning a JORC survey of the ISF slag and will report the results of this survey to shareholders when available," said chairman Alex Borrelli.

Following the tests the company has announced that, in co-operation with Kupfermelt Metal Processing, its has reached a recovery of 85% zinc and 91% lead at a leach temperature of 80°C and 75% zinc and 80% lead at an ambient temperature. It has also more than halved its sulphuric acid consumption, compared to tests run in September 2015, to approximately 500kg/t. The sulphating acid brine leach process also recovered approximately 90% of the contained vanadium from the slag/leach plant residues (LPR) composite. The IFS slag potentially contains 9000t of vanadium which is expected to be recovered in the form of vanadium pentoxide.

BMR's metallurgical partner has advised that the proposed Kabwe processing plant can in due course be modified to incorporate a sulphating acid brine leach circuit to process the slag/LPR composite. The company's strategy remains however to treat first the wash plant tailings with the acid brine leach process.
