context_page_description: Ravenswood Mining Landscape and Chinese Settlement Area is a heritage-listed former mining town and archaeological site on the reserve bounded by School Street, Cemetery Road, Railway Street and Burdekin Falls Dam Road, Ravenswood, Charters Towers Region, Queensland, Australia. It was added to the Queensland Heritage Register on 14 October 2016.
context_section_description: Located to the immediate west of the Mabel Mill Tailings Treatment area, the Partridge and Ralston Mill (see the site map) is situated between Deighton Street and Elphinstone Creek. The site retains evidence of intermittent mineral processing from the late 1930s to 1960s including:
  Cyanide tanks – two substantial round metal tanks; the on-ground cyanide agitator to the north retains its internal mechanism and the cyanide cone to the south is suspended on metal posts.
  Wilfley table site – interconnected concrete and rendered brick mounts with embedded metal fixtures, situated to the northwest of the cyanide tanks. Three vertical iron pipes protrude from ground; one encased with brickwork. Timber posts indicate the outline of the former shed. A rendered brick platform extends to the west.
  Mill shed site – timber posts indicate the outline of the shed that stood to the west of the cyanide tanks. The area contains some concrete mounts and remnant plant including: a ‘Crossley Manchester’ diesel engine (two-cylinder diesel engine with flywheel and concrete mounts); a relocated Kraut flotation unit; and a rectangular cyanide tank divided into five bays.
  Additional plant – an Oliver filter unit (north of the cyanide tanks); a small ball mill used as an amalgamation unit (north of the cyanide tanks); an Akins classifier (relocated northwest of the Wilfley table site); and a grinding pan marked ‘Langlands Foundry Co, Melbourne Limited’ (relocated east of the cyanide tanks).
  Brick settling tanks – a collection of square rendered brick tanks (two intact) and foundations, situated south of the mill shed site. Dark grey residues indicate the presence of zinc tailings. The area is dissected by a modern gravel path.
  Limonite tailings – a long narrow deposit of bright yellow / orange tailings that extends from south of the mill towards the creek to the west. A row of parallel round timber posts protrude from the tailings alignment.
