The milling process at Minera Los Pelambres reduces the size of the ore required for the subsequent flotation stage and production of copper concentrate. The extracted and crushed ore is sent to the mill grinding stage where the noise level coming from the different equipment used, makes it necessary for workers to use hearing protection. Due to the conditions in the work area that make it difficult to control the noise level, it is necessary to implement technological solutions to reduce the propagation of noise in the place where the grinding equipments are located, reducing the sound pressure levels to which workers are currently exposed.
Identify technological solutions or developments that can reduce or eliminate the propagation of noise at the source of emission and/or in the propagation medium. Solutions in the fields of insulation, conditioning or acoustic cancellation, among others, are expected without being exclusive.
Control room insulation and use of acoustic tunnels.
The following will not be considered in the evaluation process:
