The aptly named Roxbury is home to 4 types of mining industries: granite, iron, garnet and quartz. Only the first is still active, old and new quarries are located on and near Mine Hill, underlain by the Mine Hill Granite Gneiss. Iron was obtained from siderite ore in a vein on Mine Hill and smelted in a nearby furnace. Garnet was mined from porpyroblasts in schist at Green's Farm just north of the southern border and at a few prospects. The largely forgotten quartz mining took place on and just SW of Mine Hill and a mill for processing it was located on the west side of Roxbury Falls in what is now Chase Park. Quartz stockpiles and ruins are still there.
What little that is written about the mill is from an obscure publication by Bastin (1908) that incorrectly placed the mill in Roxbury Station:
At the mill the material (which is to be finely ground) is first burned in kilns to fracture it and to facilitate grinding. It is then crushed in jaw crushers, chasers, and crushing rolls, and ground in continuous-feed tube mills. After this it is graded to various degrees of fineness by air separators, which also remove most of the micaceous impurities. Some of the quartz is not finely ground but is crushed without previous burning and is graded to various degrees of fineness for use in filter beds and for sandpaper, sand belts, etc.
Harte (1945), as he did with many historic mines and mills, went looking but could not find it:
Bastin places the mill at Roxbury Station, but so far the writer not only has been unable to find anything to support that location, but he has found several persons besides himself who are reasonably familiar with the locality, who are confident it was not there. The [1938] WPA βGuide to Connecticutβ notes that βan old silica mill crumbles beside the rushing stream near an iron bridgeβ at Roxbury Falls, which may well be the mill in question.
