Wear Elements in Material Handling System, Hydrometallurgical Plant
The Open Innovation in Mining Program, EXPANDE, invites you to prequalify for a new challenge of Antofagasta Minerals S.A. and Minera Zaldivar "Wear elements in material handling system, hydrometallurgical plant ".
To participate, follow the link: https://fch.brightidea.com/AMSA182020ElementosDesgasteManejoMateriales register and upload the information requested by the enclosed technical sheet, until August 14, 2020 at 14:00 hrs (UTC/GMT -4 horas).
To look at the status of your proposal go to the challenge page https://fch.brightidea.com/AMSA182020ElementosDesgasteManejoMateriales, section "View Proposals".
The objective is to identify new wear elements made of materials and alloys resistant to corrosion, abrasion and impact break in a material handling system in the hydrometallurgical plant. The process areas involved are the ore transfer and transportation points of the crushing plant, the stacking and unloading system of tailings.
In the case of the dry area, the presence of fine material with a high content of silica added to the impacts generated by the free fall of the ore, generate premature damage to the chute plates and coatings, which affects the availability of the system demanding the use of human and financial resources in maintenance tasks.
In the case of the conveyor belt system, an acid solution is added to the crushed ore for its subsequent loading in leach pads and, once the process cycle has been completed, it is unloaded and disposed in dumps specially enabled for this purpose. For various operational and process-specific reasons, wear elements such as guard plates and others, come into contact with the crushed mineral causing damage due to the effect of corrosion.
Wear elements are required to be designed to facilitate replacement tasks, in addition to having a longer useful life under the described operating conditions.
