Turning a BLOB into PURE GOLD!

The video begins with the introduction of a large, heavy metal blob inherited by a client. Initially, the client was unaware of its composition and nearly discarded it. Instead, it was brought to the presenter's shop for examination. The presenter aims to determine if the blob is made of real gold and to quantify the amount of gold it contains. The blob weighs a substantial 533.3 grams. The investigation starts with cutting a small piece from the blob to be tested for gold purity using an acid solution in a gold tester. The metal is identified as 10 karat gold, which is 41.7% pure gold. The presenter calculates that theoretically, 222 grams of pure gold could be extracted from the blob. However, upon melting the blob, it appears not to have been fully melted, and the presenter is eager to find out the final yield after refining.

The presenter faces a challenge when the blob doesn't fit into the largest crucible and has to resort to increasing the heat. After melting, the blob separates into gold and unwanted materials. The presenter then attempts water casting, a technique used by jewelers to create organic shapes. However, the presenter realizes a mistake was made as the gold didn't separate into small pieces as intended. After rectifying the issue with a larger container, the presenter successfully creates gold flakes. The gold nuggets are then boiled in distilled water to remove impurities. The presenter also uses a filter to capture any remaining dirt, but some gold is inevitably lost in the process. The presenter ingeniously melts the filter paper with the trapped gold in a crucible, successfully reclaiming the gold. The presenter emphasizes the importance of removing all the nitric acid before proceeding to the next steps, which involve adding sodium metabisulfite to precipitate the gold out of the solution.

The presenter consolidates all the gold泥 (mud) into one place, signifying a major step forward in the process. Despite the time-consuming nature of the task, the presenter is motivated to achieve a higher purity level of gold. The video introduces 'gold refining part 2,' which involves a repeat of the entire process. Using a mixture of hydrochloric and nitric acid, known as aqua regia, the presenter dissolves the gold. The presenter then pours the mixture over ice, creating a visually stunning 'forbidden orange juice.' The presence of silver chloride indicates the necessity of repeating the refining process. The presenter uses a Stannis test to determine when all the gold has been precipitated out of the solution. After ensuring all the gold is precipitated, the presenter heats the mixture and waits for it to settle. Once confirmed that no gold remains in the solution, the presenter proceeds to clean the gold further by boiling it in distilled water and hydrochloric acid before drying it in a hot plate.

The presenter shapes the refined gold into a bar but decides it's more fitting to return it to its original blob form, creating a pure 24-karat gold blob. The mission is considered complete, with the presenter successfully extracting gold from the blob. Two questions remain: the final weight of the gold and its purity. The gold blob weighs 213.2 grams, just 9 grams less than the initial estimate of 222 grams. The presenter had the gold tested at a refinery, which confirmed it as 99% pure, exceeding the standard gold bullion purity of 999.9. Although the presenter hoped for a grading with at least three nines, they are reassured that the gold is of a higher purity than 23 karat. The video concludes with the presenter reflecting on the ambitious nature of the project and inviting viewers to subscribe for more content like this.
