Six products in the Manto CMI line, each designed for a different objective on the heap: daytime solar capture, thermal stability at depth, extended retention, day-night balance, or hydraulic control of irrigation. All are manufactured at our plants in Chile and Mexico.
Translucent 140 µm thermofilm with translucent sleeves. The base mat of the line, applicable on both the heap surface and its slopes.
Surface and/or slope
Black sleeves for maximum daytime solar capture. Delivers a greater thermal increase during the day.
Surface and/or slope
Recommended for: Sites where the objective is to maximise radiation capture during the day.
Double layer of translucent 140 µm thermofilm. Delivers more stable performance throughout the ore column, positive at the interface and at the depths assessed.
Surface
Recommended for: Sites requiring consistent thermal increase at depth.
Double layer of translucent thermofilm with black sleeves. Delivers the highest thermal retention in the line.
Surface
Recommended for: Sites where the objective is to extend the heap's cooling time.
Black thermofilm lower layer and translucent upper layer, both 140 µm. The most even day-night behaviour at the heap interface.
Surface
Recommended for: Sites with marked thermal swings, where balanced performance at the interface across the daily cycle matters.
Parallel alignment of the drip lines, free of sulfation. Reduces the risk of emitter clogging, achieves uniform flow distribution and maintains aeration in the deep zones of the heap.
Surface and/or slope
Recommended for: Critical zones and slopes, where the objective is uniformity and hydraulic control of irrigation.
