The patent application is speaking of a method and has to do with an individual trained in the art of that method which is all the law requires and therefore changing the physical properties of lead ie making it possible to be alloyed with copper or developing a lead semi-conductor has nothing to do with the mineral process again.

Grinding of alumina with a 1 mm grinding ball (1 hour) and then with 0.The E max is a new kind of ball mill designed specifically for high energy milling.The impressive speed of 2,000 min-1, thus far unrivaled in a ball mill, together with the special grinding jar design produces a huge amount of size reduction energy.
Aug 23, 2019 According to the metallurgy process, the copper ore is divided into three natural types by the ratio of copper oxide and copper sulfide.That is, sulfide ore, containing less than 10% copper oxide; oxidized ore, containing more than 30% copper oxide; mixed ore, containing 10% to 30% of copper oxide.
Dec 20, 2018 But it can inhibit natural gold.Therefore, the dosage should be strictly controlled in use, which is generally 20-200 g/t.In addition, the commonly used activators are lead nitrate, lead acetate and copper sulfate.Sulfur dioxide is also used as an activator in gold-bearing pyrite flotation abroad.
Dec 30, 2016 a old formula the french used was to add urine to the dry mix mix it real good and air dry then mill it in a powder mill had no metal parts all wood and stone then sieve for grain size had the best powder in europe ; and some one asked about putting sugar in there black powder won’t shoot worth a damn but makes simple rocket fuel ;and no the .
Jul 20, 2016 Gd 2 O 3 slurry for X-ray protection, a nontoxic replacement for lead-based material.⬢ Gd 2 O 3 is generated using a low-cost ball mill involving addition of NaCl.⬢ Dispersed-flocculated behaviour is studied to stabilise Gd 2 O 3 aqueous dispersion.⬢ An effective route is proposed to create a novel lightweight X-ray shielding matter.
Many older operations have rod mills in combination with ball mills.Ball mills are a similar shape to that of the rod mills except that they are shorter with length to diameter ratios of 1 to 1.As the name implies, the grinding media in these mills are steel balls.
Media Milling in the Ball Mill Design .Using crimp cap sealed glass vials as a more robust device, we investigated media milling in the ball mill as an alternative method to downscale the media milling process.Media milling using ball mills has been reported previously for the production of nanosuspensions [e.
Oct 31, 2019 The rotation and revolution nano-pulverizer is a batch-type wet pulverizer that can perform pulverization and disintegration into about 1 mm or less or even about 100 nm (several dozens of nm by disintegration).It is a type of planetary ball mill (planetary mill) or bead mill.
Planetary Ball Mills are used wherever the highest degree of fineness is required.Apart from the classical mixing and size reduction processes, the mills also meet all the technical requirements for colloidal grinding and have the energy input necessary for mechanical alloying processes.
