"The United Pyrites Company's Works are situated about three quarters of a mile from Spargo Brothers, and are on the northern side of the Marong road, in Pinch-gut Gully. Two processes are followed at these works, viz., the amalgamating process and the treatment by means of chlorine gas. The latter is called the Newbery-Vautin system, and the mode pursued is that laid down by Mr. Cosmo Newbery and Mr Vautin, whose names have been given to the process. Mr. Edwards manages these works. Three reverbatory furnaces are used to roast the pyrites, which is weighed in the truck before being put into the furnaces. At this weighbridge a sample of each lot is kept, and if the yield is not equal to expectation, the works are carefully gone over to see where the fault occurs. Care is taken at the furnace to regulate the heat, otherwise the pyrites might slag instead of roasting evenly right through. An immense revolving furnace (made of boiler iron) was used at these works. It was found to be suitable for treating blanket sand, but was not a success for roasting coarse pyrites. The process of amalgamating by means of Chilian mills is the same in these works as at the Western Works, but the United Works are on a larger scale, and eleven mills are utilised. It is the chlorine gas process which is most interesting here. The gas is made from sulphuric acid, black oxide of manganese, and common salt, and the gas is introduced into huge vats, where it works its way through a filter of pieces of quartz and then through the bed of roasted pyrites lying above. The action of the gas transforms the gold into chloride of gold. This is easily dissolved in water, and in that form is drawn off into huge delf jars, where the use of sulphate of iron precipitates the gold to the bottom. A small battery—eight head of stamps in two boxes—is in use here to crush small consignments of stone sent for trial. Test crushings come from all the Australasian colonies, and even from India. The jars used are manufactured at Epsom, and some of the salt used is also of home manufacture, from the Salt Lakes on the Northern plains. Mr. Edwards took us over a new building in course of erection, and in which the chlorine gas is to be generated in the midst of the pyrites— a still further advancement in the new process. There is some very good machinery in this new building, and the tailings from the ordinary pyrites works will also be treated by this chlorine gas system, which has been found to work well at Mount Morgan, in Queensland. The purest of gold is obtained by this process, the gold passing in solution into a charcoal filter, from which it emerges in the shape of metallic gold. We saw some nice cakes of retorted gold at the works. One of 26oz. was from some New Zealand pyrites (2½ tons), and assayed over 23 carats. There were also cakes of Avoca gold, of silver, and of the tremulous amalgam."

Newspaper article: A sustainable award, Diamond Valley Leader, 1 November2006, Architect and building Llewellyn Pritchard won resource Efficiency Housing Award, finalist in HIA Greensmart Building of the Year Award. House – Environmental Leader (Published: Nillumbik Now and Then /​ Marguerite Marshall 2008; photographs Alan King with Marguerite Marshall.; p186) In 2006 environmental awareness was mushrooming in the community, which is reflected in the award-winning house at Main Road near Wattletree Road, Eltham. At first sight, the building appears a mix of a classic Eltham mud-brick house and an avant-garde building style. The crown of solar panels stretching along the width of the curved roof, indicates that this is no ordinary house. In fact it signals a new building trend of minimal impact on the environment. Yet it utilises the environment with high technical expertise to achieve comfort and cut running and maintenance costs. In recognition of this, its designer/builder, Conscious Homes, won the 2006 National HIA Greensmart Resource Efficiency Award. For Conscious Homes director, Llewellyn Pritchard, this house reflects a philosophy, strengthened by his connection with Aboriginal culture, through his foster siblings. Pritchard believes the sustainable way indigenous Australians lived and their spiritual connection with land, demonstrates how humanity is part of the ecology. His interest in environmental design stemmed from growing up in bushy Eltham Shire, with its mud-brick tradition. This was followed by studying Architecture at RMIT in the early 1980s, and learning about passive solar design. Pritchard says this house demonstrates that environmental sustainability is not about sacrifice, but about exceptional levels of occupant comfort, savings in running costs and modern fittings and appliances.1 The solar panels on the north roofs are intentionally obvious to make a statement about what the building is doing. But inside the systems are hidden and interactive with conventional services, such as the underground water tank. The house is water and energy self-sufficient and at 12 squares is much smaller than conventional houses, to minimise resources. Yet it accommodates his family of four with three bedrooms, a living/dining and kitchen area and a bathroom/laundry. Importantly the building is designed to last hundreds of years, by being able to be modified as the need arises, such as for commercial use. In this way the structure minimises its environmental impact. The solid double mud-brick walls (which are insulated) include steel beams and supporting frame, allowing the future removal or alteration of any section. The materials are local, recycled and of low toxicity where possible.2 Inside and out, the mud-brick is rendered and sealed with a combination of cement and sand and a mud-based coating in a soft golden hue increases its life. Inside, the golden-brown timber is plantation Mountain Ash and the concrete floors throughout – of local stone aggregate with a clear seal – have a natural looking random stone appearance. The house sustains a stable temperature of around 20 degrees, assisted by the concrete slab floor. The many large double-glazed windows and highlights (windows set high on walls) provide cross-flow ventilation. The north-facing living area maximises heating from the lower winter sun and is cooler in summer, because the sun is higher. Heating comes from a solar hydronic slab system. All appliances and fittings are high efficiency energy or water rated. Appliances in the timber kitchen include a gas stove and a dishwasher, using the building’s own power and water. French doors open from the living area to a deck, concealing the treatment system for all waste water. This is pumped through sub-soil drippers to the indigenous garden beds and no-dig vegetable patch. Below the carport is the 80,000-litre rainwater tank and at the back, the boiler room houses the solar boiler, water tank access, domestic water supply pump, filter gear and hydronic slab heating controls. The solar system is backed up with gas, which is needed to heat water only in winter. Gas used is less than one quarter of that for an average home with ducted heating. Excess power is fed back to the grid and the building uses about one quarter of the mains electricity of an average home. Other local builders have followed Pritchard’s lead in resource efficiency for minimal environmental impact.main road, eltham, businesses, llewellyn pritchard, hia greensmart building of the year award., efficiency housing award, conscious homes australia pty ltd
