· Fill a spray bottle and liberally spray the white mold of the affected plant leaves and stems. Let the plant dry. Repeat as necessary until the white powdery mildew has gone. If the baking soda solution seems ineffective, then you can try using potassium bicarbonate as a more powerful antifungal spray.
· According to the survey, the concentration of Pb and Zn in the mining area of Lanping county was 56 and 47 times higher than the world average level, the untreated wastewater had a great impact on the soil (Yanqun et al. 2005; Zeng et al. 2014; Zuran et al. 2019a; Zuran et al. 2019b ).
The precipitating reagent is added at a concentration that favors the formation of a "good" precipitate (see below). This may require low concentration, extensive heating (often described as "digestion"), or careful control of the pH. Digestion can help reduce the amount of coprecipitation.
· 1 Wash, filter and grind the granite ore with into smaller pieces. 2 Put the ground ore into a tank containing a dilute cyanide solution and add zinc. The chemical reaction between a dilute cyanide solution and zinc will separate the gold from the ore. 3 Use a filter press to remove the gold from the solution.
The following steps need to be undertaken to establish bioleaching potential of goldbearing ores and concentrates. • Determination of pregrobbing and refractoriness of the ore/concentrate. • Sequential diagnostic tests to determine nature and extent of gold tiedup with different sulfide and nonsulfide mineral constituents. •

· CIL circuit is a process of continuous leaching of gold from ore to liquid and countercurrent adsorption of gold from liquid to carbon particles in a series of tanks. The CIL process concentrates gold from – g/t in ore to 2000 to 6000 g/t on carbon.
gold processing, preparation of the ore for use in various products. For thousands of years the word gold has connoted something of beauty or value. These images are derived from two properties of gold, its colour and its chemical stability. The colour of gold is due to the electronic structure of the gold atom, which absorbs electromagnetic radiation with wavelengths less .

Oro Industries has reintroduced the Helix Spiral and other specialized gold recovery equipment for international sales and distribution. The Helix Spiral is currently being sold in parts of Central and South America and Asia from our Costa Rica operation and is now being offered in the US and Canada based out of Yuba County, California.
· Enzymelinked immunosorbent assay (ELISA) is a labeled immunoassay that is considered the gold standard of immunoassays. This immunological test is very sensitive and is used to detect and quantify substances, including antibodies, antigens, proteins, glycoproteins, and hormones. The detection of these products is accomplished by complexing antibodies and .
Metal accumulating plant species can concentrate heavy metals like Cd, Zn, Co, Mn, Ni, and Pb up to 100 or 1000 times those taken up by nonaccumulator (excluder) plants. In most cases, microorganisms bacteria and fungi, living in the rhizosphere closely associated with plants, may contribute to mobilize metal ions, increasing the bioavailable fraction.

UF to a 10× volume concentration factor is followed by constant volume DF using diavolumes of water and then a final concentration by 4× yielding a 40× volume concentration factor overall.
Gold is widely distributes on the earth at a background level of g/1000 kg ( ppm by weight). Its interness and its high density causes it to concentrate in streambeds, either in small flakes or in larger nuggets, from which it may be recovered by panning. It is found free in nature and associated with quartz, pyrite and other minerals.
nominal throughput of 500000, t/year through a hybrid carboninleach (CIL) plant to recover gold as bullion. Sulphide ores will be treated at a nominal throughput of 250,000 t/year through a conventional froth flotation plant to produce a coppergold concentrate. A block diagram showing the overall flow sheet is shown in Figure 1.
