Microcline (v. Amazonite) -- cleaned Lake George area, Park County, Colorado, USA 130 x 124 x 104 mm Classic, old-time Colorado Amazonite with sharp, light greenish-blue, blocky crystals of Microcline, on a matrix of white Albite (v. Cleavlandite). The Amazonites are well formed and fully terminated, several of which are well-developed twins. One crystal has a "slot" where it once enclosed a blade of what was likely Cleavlandite. This is an old AE Foote specimen, and was later sold by Filer’s (Redlands, CA) and the Bradleys (Los Angeles). Formerly in the Don Boydston and Joel D. Cohen collections. It is complete on all sides, unrepaired and has no damage. (Author: GneissWare)

Morenosite is a yet unproven in the S Wales coalfield.

MILPILLAS MINE BY NIGHT AND BY DAY These photographs capture groundbreaking moments at the Milpillas Solvent-Extraction and ElectroWinning plant, presenting both night and day perspectives. Prominently featured in the upper right section of the images are the crushed Copper ore leach pads and the associated ponds, which are notably rich in acid-leached Copper solution. The building at the top, the one closest to the heap leach pads is the electrowinning plant. Commissioned in 2005, this advanced facility was the outcome of a significant partnership between Outokumpu Technology, a leader in metallurgical solutions, and Industrias Peñoles. Outokumpu’s extensive involvement ensured the plant, initially designed for 45,000 tons of high-purity Copper cathodes annually (with an expansion to 65,000 tons by 2008), would be a success for Compañía Minera La Parreña. Like its counterpart in Laos, Milpillas didn’t just become part of Mexican mining history; it also perfectly illustrated the significant technological shifts in Copper production at the turn of the millennium. Unlike many mines that produce Copper concentrate, Milpillas produced high-purity Copper cathodes through a sophisticated process of underground mining, heap leaching, solvent extraction (SX), and electrowinning (EW). This integrated approach bypassed the need for smelting and refining elsewhere, streamlining the journey of Copper from its ore state to a commercially valuable product.

MILPILLAS MINE BY NIGHT AND BY DAY

MILPILLAS UNDERGROUND - STORAGE ZONE The nature of the Milpillas mine’s underground drives and storage areas was intrinsically linked to its “cut-and-fill” mining method and the unique geological characteristics of the deposit. The mine’s infrastructure consisted of a network of drives (tunnels) excavated to access and extract the ore. These drives were carefully designed to follow the complex ore bodies, which included lenticular, flat-lying oxide zones at varying elevations, as well as deeper supergene sulphide zones. The underground layout facilitated the movement of equipment, personnel, and ore, as well as providing ventilation and drainage. To maintain ground stability in the created voids, waste material or cemented fill was introduced, creating a new working platform for the next mining cycle. This systematic approach allowed for selective extraction, maximizing recovery of the valuable Copper while ensuring operational safety and efficiency. Storage areas underground are typically integrated into the mining cycle. After extraction, ore was crushed within the mine and then transported to surface leaching yards. Given the “cut-and-fill” method, excavated areas were often backfilled with waste material after ore removal, contributing to ground stability. While specific storage capacities for raw ore underground are not widely detailed, the efficient flow of material from extraction to surface processing implied a well-managed system for temporary holding and transport within the mine’s extensive network of tunnels. A significant challenge for underground operations at Milpillas was water management, as the mine historically faced issues with flooding due to groundwater infiltration. Efficient pumping systems were crucial to dewater the mine and ensure safe and continuous operations. Once the ore was extracted, it is brought to the surface for further processing.
